[AusNOG] [v6z] Why you shouldn't worry about switching to IPv6 now

[Michael Biber]

Been saying for years that IPv4 will endure while the pain of supporting
both protocols is manageable (be that cost, NAT, security, troubleshooting,
OAM or wherever the pain exists). There will come a time when it is no
longer bearable and wholesale conversion to v6 only will become the norm.
Optimistically...5 years, ... pessimistically? ...maybe 15 years. Vint Cerf
once said that he expected v4 to endure in the 'net for a further 40 years.

the real point is that with IPv4 exhaustion, 'new' sites on the internet may
be IPv6-only addresses.

the article author seems to assume that every ISP will magically provide
means for IPv4-only customers to connect to IPv6-only sites - for those
customers that aren't dual-stack CPE capable.
i think thats a damn big assumption.


cheers,
