That is, the second field above is just written as "0" rather than " Each hex digit is 4 bits and can represent a hex value of 0-F. This means that there are 16 bits in each field 4 hex digits x 4 bits per digit.

Next Page Internet Protocol version 6 is a new addressing protocol designed to incorporate all the possible requirements of future Internet known to us as Internet version 2. Along with its offering of an enormous amount of logical address space, this protocol has ample features to which address the shortcoming of IPv4.

Why New IP Version? So far, IPv4 has proven itself as a robust routable addressing protocol and has served us for decades on its best-effort-delivery mechanism.

At the time of its birth, Internet was limited only to a few universities for their research and to the Department of Defense.

Why Not IPv5?

IPv4 is 32 bits long and offers around 4,, addresses. This address space was considered more than enough that time. Given below are the major points that played a key role in the birth of IPv6: Internet has grown exponentially and the address space allowed by IPv4 is saturating.

There is a requirement to have a protocol that can satisfy the needs of future Internet addresses that is expected to grow in an unexpected manner. IPv4 on its own does not provide any security feature. Data has to be encrypted with some other security application before being sent on the Internet.

Data prioritization in IPv4 is not up to date. Though IPv4 has a few bits reserved for Type of Service or Quality of Service, but they do not provide much functionality.

IPv4 enabled clients can be configured manually or they need some address configuration mechanism. It does not have a mechanism to configure a device to have globally unique IP address.

Till date, Internet Protocol has been recognized has IPv4 only.

Version 0 to 3 were used while the protocol was itself under development and experimental process. So, we can assume lots of background activities remain active before putting a protocol into production. Similarly, protocol version 5 was used while experimenting with the stream protocol for Internet.

It is known to us as Internet Stream Protocol which used Internet Protocol number 5 to encapsulate its datagram. It was never brought into public use, but it was already used. Here is a table of IP versions and how they are used: Taking pre-cognizance of the situation that might arise, IETF, ininitiated the development of an addressing protocol to replace IPv4.[contact-form-7 id="" title="Contact form 1"].

General IPv6 Notes. Skip to end of metadata. Note: When adding IPv6 to a child zone, you must add both the global address as well as a link-local address.

Short Notes on IPv6 ~ Sysnet Notes

Solaris will not automatically assign a link-local address for a child zone as it does for the global zone. In short, guest VMs support IPv6, but IPv6 checksum offload isn't supported.

With IPv6 CIDR defined by RFC , instead of blocks of IP addresses being assigned in powers of , blocks will be assigned in powers of 2 — making more efficient use of the available address space. Enter the size of each subnet in the “ Subnet size (/nn)” column.

Please specify the size using IPv6 slash notation (for example, /48). In the “ Purpose” column, write a short .
