IPv6 increases the IP address size from 32 bits to how many bits?

IPv6 will increase the address space to 128bits. This will allow for around 3.4x1038 unique addresses. That's a lot. More then we could likely use in the foreseeable future. Of course we said that about IPv4 as well.

What advantages does IPv6 have over IPv4?

ip6 can handle many more addresses than ip4 - allowing more people to join the Internet.

How can DNS distinguish between an IP version 4 and IPv6 host in determining which resource record to return?

Windows Embedded CE resolves host names into IPv6 addresses via queries to a DNS or WINS server, or via IPv6 link local multicast. Queries sent to DNS servers are performed over IPv6 and IPv4. Queries sent to WINS servers are performed over IPv4 even though they may return IPv6 addresses. To use a host name as an alias for an IPv6 address, you must ensure that the name is unique and that it resolves to the correct IPv6 address. For IPv6 name-to-address entries, the IPv6 address is written by using standard colon-hexadecimal format. For more information, see IPv6 Addresses. When using the getaddrinfo function, dual stack name resolution occurs. Domain names are resolved by sending DNS name queries to a configured DNS server. This is a computer that either stores domain name-to-IPv6 address mapping records or has records of other DNS servers. The DNS name resolution may yield both IPv4 and IPv6 addresses. The DNS server resolves the queried domain name to an IPv4 or IPv6 address and returns the results. When configured for DHCP, the DHCP server provides IPv4 addresses of DNS and WINS servers used for both A and AAAA searches. The DNS client in Windows CE .NET 4.1 and later also supports the processing of AAAA (quad-A) resource records. The Internet Protocol (TCP/IP)must be configured with the IPv4 address of a DNS server. The Host name is resolved to an address by a DNS, WINS, or Link Local Multicast Name Resolution (LLMNR) resolver

Does Windows XP support IPv6?

Short answer - yes.You need to be running Service Pack 1 at a minimum.Service Pack 2 has an even more complete IPv6 stack.To enable IPv6 on XP, open a command prompt window and type:C:\> ipv6 /?Did you then see this result?:C:\> ipv6 /?Could not access IPv6 protocol stack - the stack is not installed.To install, please use 'ipv6 install'.If you did get the above result, simply type:C:\> ipv6 installIt will take a few seconds, and then your Windows XP system will be fully IPv6 enabled.

How the quality of service and security achieved in IPV6?

IPV6 only allows more nodes (~64K times as many) on the internet than the existing IPV4 does. It has no effect on security.

What is the difference between IP4 and IP6?

IPv6 is based on IPv4, it is an evolution of IPv4. So many things that we find with IPv6 are familiar to us. The main differences are:1.Simplified header format. IPv6 has a fixed length header, which does not include most of the options an IPv4 header can include. Even though the IPv6 header contains two 128 bit addresses (source and destination IP address) the whole header has a fixed length of 40 bytes only. This allows for faster processing.Options are dealt with in extension headers, which are only inserted after the IPv6 header if needed. So for instance if a packet needs to be fragmented, the fragmentation header is inserted after the IPv6 header. The basic set of extension headers is defined in RFC 2460.2.Address extended to 128 bits. This allows for hierarchical structure of the address space and provides enough addresses for almost every 'grain of sand' on the earth. Important for security and new services/devices that will need multiple IP addresses and/or permanent connectivity.3.A lot of the new IPv6 functionality is built into ICMPv6 such as Neighbor Discovery, Autoconfiguration, Multicast Listener Discovery, Path MTU Discovery.4.Enhanced Security and QoS Features.Answer:IPv4 means Internet Protocol version 4, whereas IPv6 means Internet Protocol version 6.IPv4 is 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses. IPv4 can support up to 232 addresses, however the 32 bits IPv4 addresses are finishing to be used in near future, so IPv6 is developed as a replacement.IPv6 is 128 bits, can support up to 2128 addresses to fulfill future needs with better security and network related features. Here are some examples of IPv6 address:1050:0:0:0:5:600:300c:326bff06::c30:0:0:0:0:0:192.1.56.10The most important difference is that it has a larger address space. IPv6 uses 128 bits, instead of the 32 bits used in an IPv4 address.There are also some changes in the header format, and some additional options, like built-in security options. These can be added to IPv4 through additional protocols, so this is really no big deal.IPv4 is like 10.36.05.2 while IPv6 is one huge garble.IPv4 is a 32 bits IP address that we use commonly, it can be 192.168.8.1, 10.3.4.5 or other 32 bits IP addresses.

IPv4 uses 4 bytes; IPv6 uses 16 bytes for the address.Mainly, IPv6 has a larger addressing space; IPv6 addresses use 128 bits instead of 32 bits.

Can you use IPv6 now?

IPV6 is being used in most (If not all) Govermental Bodies, ISPs, Large enterprise networks, Some early adopting medium sized networks, and a few lower end networks like the one I am running at home. IPV6 has been around for a few years now and will take several more for a complete rollout.

What is the ipv4 and ipv6?

What we have used up to now(IPv4) has been used up(32 bit). With new devices adding in to the network we need a bigger address space.So IPv6 comes with lot of extended capabilities like,Expanded address spaceExpanded routing capabilitiesSimplified header formatSupport for authentication and privacyQuality of service (QoS) capabilitiesNOTETime taken by a packet to reach the destination from the source, we call it "Delay". Variation of that delay we call as "Jitter". Jitter is dangerous much more than delay. We have to reduce it to provide QoSIn IPv6 Packet we see no of header fieldsTraffic Class - This contain a number which represent the priority level this is what make QoS possible.Flow Label - Contain a small no which is easy to handle This make routing faster and easy.In IPv6 we find 128 bit address. There are there kinds of addressesUni-cast = A packet with a uni-cast address to a single interface identified by that address. ID for single interfaceAny-cast = ID for group of interfaces. But packet will be delivered to the nearest one.Multi-cast = ID for group of interfaces.

What are the three parts of an IPv6 address?

Answer: Unicast, Anycast and Multicast.There are three types of IPv6 addresses, unicast, multicast, and anycast addresses.The unicast and multicast addresses are similar to the IPv4 versions. However, IPv4 broadcast address is no longer supported and is replaced with a new type of address called anycast.UnicastUnicast is an identifier for a single interface. A packet sent to a unicast address is delivered to the interface identified by that address. A node can have more than one IPv6 network interface. Each separate interface must have its own unicast address associated with it. Contained in the 128-bit field is an address that identifies one interface.3138241664 bitsFPTLA IDRESNLA IDSLA IDInterface ID· FP. The format prefix is the three-bit prefix to the IPv6 address that identifies where it belongs in the IPv6 address space.· TLA ID. The top-level aggregation identifier contains the highest-level routing information of the address. This refers to the grossest level of routing information in the internetwork, and as currently defined (at 13 bits) there can be no more then 8192 different top-level routes.· RES. The next eight bits are reserved for future use.· NLA ID. The next-level aggregation identifier is 24 bits long, and it is meant to be used by organizations that control top-level aggregation Ids to organize that address space.· SLA ID. The site-level aggregation identifier is the address space given to organizations for their internal network structure. With 16 bits available, each organization can create its own internal hierarchical network structure using subnets in the same way they are used in IPv4. As many as 65,535 different subnets are available using all 16 bits as a flat address space. Using the first eight bits for higher-level routing within the organization would allow 255 high-level subnets, each of which has as many as 255 sub-subnets.· Interface ID. This 64-bit field contains a 64-bit value based on the IEEE EUI-64 interface IDMulticastMulticast is an identifier for a set of interfaces (typically belonging to different nodes). A packet sent to a multicast address is delivered to all interfaces identified by that address. As soon as the first few bytes of a packet are received the node checks to see if the destination address is at the beginning of the transmission. If the destination address is the same as the node's interface address then the node will pick up the rest of the transmission. This makes it relatively simple for a node to pick up on broadcast and multicast transmissions. If a broadcast is sent then the node will listen. For multicasts, the node subscribes to a multicast address, and if it senses that the destination address is a multicast address, it must determine if it's a multicast address to which the node is then subscribed. When a node subscribes to a multicast address, it announces that it wants to be a member and any local routers will subscribe on behalf of that node. When a transmission is sent to that multicast address from another node that is on the same network, the IP multicast packet is encapsulated into a link layer multicast data transmission unit. The IPv6 solution to the broadcast problem is to use an "all nodes" multicast addresses to replace those broadcasts that are absolutely necessary, while resorting to more limited multicast addresses for other situations in which broadcasts were previously used. Below is an IPv6 multicast address format, from RFC 2373.844112 bits11111111FlagsScopeGroup IDThe first octet, which is all ones, identifies the address as a multicast address. Multicast addresses include a full 1/256th of the IPv6 address space, as shown above. The rest of the multicast address consists of three fields:· Flags. This is actually a set of four single-bit flags. Only the fourth flag is currently assigned, and it represents whether or not the address is a well-know multicast address that has been assigned by the Internet numbering authority or is a temporary multicast address. If this flag is set to zero, it means the address is well-known; being set to one signifies a transient address. The other three flags are currently being reserved for future use.· Scope. This four-bit field contains a value that indicates what the scope of the multicast group is. Whether the multicast group can include only nodes on the same local network, same site, same organization, or anywhere within the IPv6 global address space. Possible values range from 0 to 15 (hexadecimal) in table below.HexDecimalValue00reserved11node-local scope22link-local scope33(unassigned)44(unassigned)55site-local scope66(unassigned)77(unassigned)88organization-local scope99(unassigned)A10(unassigned)B11(unassigned)C12(unassigned)D13(unassigned)E14global scopeF15reserve· Group ID. This 112-bit field identifies the multicast group. The same group ID can represent different groups, depending on whether the address is transient or well known, and also depending on the scope of the address. Permanent multicast addresses use assigned group ID's with special meaning, and the membership in such groups will depend both on the group ID and on the scope.AnycastAnycast is an identifier for a set of interfaces (typically belonging to different nodes). A packet sent to an anycast address is delivered to one of the interfaces identified by that address (the "nearest" one, according to the routing protocols' measure of distance). All nodes that are members of a multicast address expect to receive all packets sent to that address. A router that connects five different local Ethernet networks will forward a copy of a multicast packet to each of those networks. Anycast is the same because multiple nodes may be sharing the anycast address, like a multicast address but different since only one of those nodes can expect to receive a datagram sent to the anycast address.Address FormatIPv6 addresses are now four times as long as an IPv4 address. The IPv4 address is represented as X.X.X.X, where the "X" is any number from 0-255. IPv6 address on the other hand is in the form X:X:X:X:X:X:X:X, where X refers to a four-digit hexadecimal integer (16 bits). For example, a few valid IPv6 addresses are as follows:CFAE:3290:ABCD:1234:CEAF:5678:9012:AAAAABC3:0000:0000:0003:ABCD:0123:FFFF:ABCDThe above IPv6 address could also be represented asABC3::3:ABCD:123:FFFF:ABCDNote that the integers are hexadecimal integers, so the letters A through F represent the digits 10 through 15. Each integer must be included, but leading zeros are not required. In addition, a double colon (::) can be used once in an address to replace multiple fields of zeros. For example:1000:0:0:0:0:0:0:1could be represented as1000::1The double colon means that the address should be expanded out to a full 128-bit address. This method replaces zeros only when they fill a complete 16-bit group, and the double colon can be used only once in any given address.IPv6 HeadersThe new IPv6 header structure has a header boundary at 64-bits and has only 40 bytes, where 32 of them are used for IPv6 addresses and the remaining 8 bytes by 6 additional fields. Whereas IPv4 headers are terminated on a 32-bit boundary and consist of 24 bytes, where 8 of them are used for IPv4 address and the remaining 16 bytes by 12 additional fields. IPv6 headers do not contain any optional elements. If additional functions are need IPv6 uses extension headers. This makes the new IPv6 header much simpler then its predecessor.

How many numbers do a ip number have?

An IPv4 address has four groups of digits from 0 to 255 (256 total in one group which is equal 2^8), so it could vary from 0.0.0.0 to 255.255.255.255 Total length of IPv4 address space is 2^32 = 4,294,967,296 total addresses. An IPv6 address has eight groups of four hexadecimal digits from 0 to ffff (65,536 total in each group which is equal 2^16), so it could vary from 0:0:0:0:0:0:0:0 to ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff Total length of IPv6 address space is 2^128 = 340,282,366,920,938,463,463,374,607,431,768,211,456 total addresses, which means it's more than 4,8 * 10^28 of addresses for each of 7 billion people on the planet.
