"It's hard to fathom why Cisco hasn't added IPv6 to its Linksys
consumer routers yet, but the company has promised support will
come this spring.
"It's 2011, IPv4 addresses are officially exhausted, and the
world's largest router maker, Cisco, still doesn't support IPv6 in
its best-selling line of Linksys wireless routers. This is true
even for the new E4200 router released just last month (priced at
$180). The company has promised to have IPv6 support for the
Linksys line by the spring but has not been specific.
"The networking world has been aware of the IPv4 address
shortage for years. Cisco's competitors D-Link and Netgear, for
instance, have been offering certified IPv6 consumer routers for a
while. Cisco's enterprise routers support IPv6 (naturally) and have
also been certified by the IPv6 Forum."
