Rough Guide to IETF 97: All About IPv6

In this post for the Internet Society Rough Guide to IETF 97, I’ll take a look at some recent IPv6 activity and what’s happening at IETF 97 in Seoul next week.

It’s been a good year for IPv6 with several sources indicating that global IPv6 adoption rates have increased by nearly 50% during 2016, with a number of large ISPs, mobile operators and content providers actively deploying the protocol. Whilst IPv6 has been supported by major operating systems for some time, native IPv6 is also increasingly being supported by applications and networks, thus reducing reliance on transition mechanisms and tunnelling. This in turn is improving the performance and reliability of IPv6, therefore increasing the chances of establishing an IPv6 connection in preference to one using IPv4.

IANA has recently been able to allocate an additional /18 from the recovered pool of IPv4 to each of the Regional Internet Registries, and has further allocations planned every six months until March 2019. However, if no more blocks are returned, then this will be the last allocation of IPv4 addresses. Furthermore, network operators have increasingly been running into limitations with the available size of private IPv4 space, especially for mobile markets and upon acquisition of other operators using overlapping addresses.
