Reasons for servers to support IPv6
It's good to wonder publicly and have a discussion!I set up IPv6 on all my servers in 2001 and thought we'd all be on IPv6 in just a couple of years :PWhat's interesting is how much resistance there is to adding IPv6 which comes from entrenched IT. People who never learned (much) about IPv6 seem to be afraid of it and often respond with some variant or another of "don't fix it if it ain't broke", or "it's extra work for no return", or "we'll have to pay licensing to add IPv6 because we bought crap routers, so let's not", et cetera.My favorite is, "we have no record of people trying to use IPv6" - yes, that's real :DIt just shows their ignorance. Adding IPv6 has myriad advantages - no need for NAT, proxies or port forwards to share addresses, no need to renumber networks if allocations or upstream change, redundancy, valid security-through-obscurity (imagine port scanning a /64 looking for open ssh ports)...What's really interesting is how many of these "we fear change" IT people don't realize they're already using IPv6 on their phones every day, with a majority of the sites they visit.
