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.

How many bytes are in ipv6?
IPv6 address is 128-bit. IPv6 addresses are written in eight groups of four hexadecimal digits separated by colons, such as 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
How many bits in an IPv4 address?
Pv4 uses 32-bit (four-byte) addresses. which limits the address space to 4,294,967,296 (232) possible unique addresses. However, some are reserved for special purposes such as private networks (~18 million addresses) or multicast addresses (~270 million addresses). This reduces the number of addresses that can potentially be allocated for routing on the public Internet. As addresses are being incrementally delegated to end users, an IPv4 address shortage has been developing.
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.

How many bits in an IP V6 address?
128 Bits. An IPv6 address is made up of 8 fields consisting of 16 bits per field. If you multiply 8 x 16 will get 128 bits. Each field is separated by colons unlike IPv4 which was separated by dotted decimal notation. A good link to go to to see the address and how sub-netting is done is on the related links below.
