IPv6 on SOHO routers?
by Frank Bulk - iNAME 14 Mar '08

14 Mar '08

Slightly off-topic, but tangentially related that I'll dare to ask. I'm attending an "Emerging Communications" course where the instructor stated that there are SOHO routers that natively support IPv6, pointing to Asia specifically. Do Linksys, D-Link, Netgear, etc. have such software for the Asian markets? Furthermore, he stated that networking equipment companies like Cisco will be moving away from IPv4 in 5 years or so. This is the first time I've heard this posited -- I had a hard believing that, but he claims it with some authority. Anyone hear anything like this? My own opinion is that we'll see dual-stack for at least a decade or two to come. Frank
