True or False If your network does not need or use APIPA it must be uninstalled to avoid conflicts?
FalseEven if your network does not need or use APIPA, leaving it enabled is not necessarily problematic, because APIPA is designed to first check for the presence of a DHCP server and allow the DHCP server to assign addresses. In addition if a computers IP address has been assigned statically, APIPA does not reassign a new address. It only works with clients configured to use DHCP. APIPA can be disabled ,However, by editing the Windows operating system registry.
What are the methods of assigning IP addresses to a workstation?
Method 1: Manually assign an IP address. You can manually assign an IP address, network mask, and even DNS servers to a particular network interface. This is useful if you need the IP address to always be the same, or if you have no DHCP server. (See #2). It has the disadvantages of requiring the network administrator to keep track of the manual IP address in order to prevent conflicts, and also requires manually changing it when necessary. Method 2: DHCP. This is the most common way of assigning IP addresses. A DHCP server (DHCP = Dynamic Host Configuration Protocol) receives a request from a workstation, consults an internal list of available and assigned IP addresses, and then responds with an IP address and other information such as DNS servers and default gateways. This has the advantage of being very easy to use, and requires a lot less work on the part of the network administrator. However, if the server or service is unavailable for some reason, computers may not have the ability to set up their addresses except for APIPA. (See #3). Method 3: APIPA (Automatic Private IP Addressing, a.k.a. Zero Configuration Network). This isn't really a method per se. If your computer is unable to contact a DHCP server and has not been manually configured, it may set up an APIPA address. It assigns itself a random address in the range of 169.254.0.0/16. (169.254.0.1 - 169.254.255.254).
How millions of computers are addressed with just 32 bits?
Internet addresses of computers are currently covered by Internet Protocol version 4 (IPv4), which has a 32 bit address space.Imagine you had only 1 bit long addresses. Then you could have only 2 different addresses - address 0 and address 1. But if you had 2 bit long addresses, you get 4 possible addresses - 00, 01, 10, 11. If you had 3 bit long addresses, you would have 8 possible addresses - 000, 001, 010, 011, 100, 101, 110, 111. Every time you add a new address bit, you double the number of addresses possible.1 bit = 2 addresses2 bits = 4 addresses3 bits = 8 addresses4 bits = 16 addresses5 bits = 32 addresses...Since each address bit doubles the number of possible addresses, a 32 bit address space covers 232 possible addresses, or over 4,000,000,000. And this is only for unique addresses that the whole world can use; many computers are in private networks (inside corporations, for example) and do not need an external IPv4 address. They talk to the outside world through a few routers which DO have IPv4 addresses. So a company might have tens of thousands of computers, but only a few dozen IPv4 addresses that are assigned to the routers they have connected to the internet.Even so, all 4,000,000,000 of the IPv4 addresses have finally been allocated and will be used up over the next several months. This means that the internet will need to migrate to a newer addressing version, IPv6. IPv6 uses 128 bit addressing. 2128 is about 3.4x1038 addresses. That's 3,400,000,000,000,000,000,000,000,000,000,000,000,000 addresses. They should last us a while.
A processo n Host t has been assigned port P and a process on Host 2 has been assigned port Q ls it possible for there to be two or more TCP connections between these two ports at the same time Ex?
monash...
When was ipv6 coming?
it all ready is on most routers and NICs available when it becomes the standard idk but if you open command line and use the ipconfig command you can see if you have and ipv6 address and if you do it'll display what it is

How are IP addresses assigned from a pool of IP addresses?
That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned. Any time a host (computer or similar) requests an IP address, the DHCP server will assign an available address and mark it, in its memory, as "assigned" so it won't assign the same address to another computer.That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned.

What is composed of the remaining addresses within a dhcp scope once all exclusion ranges have been applied?
The remaining addresses form the Available Address Pool which can then be dynamically assigned to DHCP clients
How does apipa works?
Short for Automatic Private IPAddressing, a feature of later Windows operating systems. With APIPA, DHCP clients can automatically self-configure an IP address and subnet mask when a DHCP server isn't available. When a DHCP client boots up, it first looks for a DHCP server in order to obtain an IP address and subnet mask. If the client is unable to find the information, it uses APIPA to automatically configure itself with an IP address from a range that has been reserved especially for Microsoft. The IP address range is 169.254.0.1 through 169.254.255.254. The client also configures itself with a default class B subnet mask of 255.255.0.0. A client uses the self-configured IP address until a DHCP server becomes available.The APIPA service also checks regularly for the presence of a DHCP server (every five minutes, according to Microsoft). If it detects a DHCP server on the network, APIPA stops, and the DHCP server replaces the APIPA networking addresses with dynamically assigned addresses.APIPA is meant for nonrouted small business environments, usually less than 25 clients.
What is APIPA IP address?
APIPA, also known as Automatic Private IP Addressing, is a feature used in Windows operating systems. It comes into action only when DHCP (Dynamic Host Configuration Protocol) servers are available. When the DHCP client first comes on, it will try to establish a connection with the DHCP server in order to get an IP address. It is when this server is (or at a later point becomes) unavailable, that APIPA will kick in.As the client is unable to connect with the server, APIPA will automatically try to configure itself with an IP address from an specially reserved range. (This reserved IP address range goes from 169.254.0.0 to 169.254.255.255).After an IP address is obtained using APIPA, the client will then verify that their IP address is a unique one on the LAN. This is done utilizing ARP. According to Microsoft guidelines, APIPA will also check regularly to see whether the DHCP servers are available. If at any point it does become available, then the APIPA service will discontinue itself de-allocating the IP address it has obtained, and allow the DHCP server to allocate a dynamic IP address.When APIPA takes over and your client has been assigned an IP address, the client will be able to communicate with other computers also on that LAN which have also been configured by APIPA, or failing that, which have been assigned a static IP address in the range mentioned earlier (so and IP address like 169.254.x.x, where ".x.x" are the identifiers unique to that particular computer).However, if you are connected to the internet without a NAT, or even a proxy server, or you use routers, you might want to turn the APIPA feature off. For more information on this you can go to straight to the source at Microsoft's Help and Support pages on "How to use automatic TCP/IP addressing without a DHCP server" at this address http://support.microsoft.com/kb/q220874/All the information you need to on how to turn APIPA off, is contained here.In essence the APIPA service is a fail-safe device put in place by Microsoft to make sure that everything runs smoothly. There is nothing that you need to do about it as it all happens in the background, and at speeds and times of which you are unaware of. In fact, by the time you detect that your DHCP server is unavailable, and you try to rectify the matter, APIPA would have already taken the proper steps necessary to keep your client running smoothly.
Developed to slow the exhaustion of IP addresses?
The use of NAT, combined with private IP addresses, can help reduce the waste of IP (version 4) addresses.However, even with the use of NAT, some time in 2010 or 2011, the last IPv4 addresses will have been assigned, and there will be more pressure to use the new protocols (IPv6 and related protocols).The use of NAT, combined with private IP addresses, can help reduce the waste of IP (version 4) addresses.However, even with the use of NAT, some time in 2010 or 2011, the last IPv4 addresses will have been assigned, and there will be more pressure to use the new protocols (IPv6 and related protocols).The use of NAT, combined with private IP addresses, can help reduce the waste of IP (version 4) addresses.However, even with the use of NAT, some time in 2010 or 2011, the last IPv4 addresses will have been assigned, and there will be more pressure to use the new protocols (IPv6 and related protocols).The use of NAT, combined with private IP addresses, can help reduce the waste of IP (version 4) addresses.However, even with the use of NAT, some time in 2010 or 2011, the last IPv4 addresses will have been assigned, and there will be more pressure to use the new protocols (IPv6 and related protocols).

Who has managed all public IP addresses since 1982?
The IANA, or Internet Assigned Numbers Authority, is the organization that has been managing IP addresses since even before it was known by an official name. A registry function that would become IANA was in place by the 1970s, managed by the famed Jon Postel (of USC's Information Sciences Institute). Today IANA is managed by ICANN, the Internet Corporation for Assigned Names and Numbers. See the accompanying links for IANA, ICANN, and more on the history of IANA.
