Re: [IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEP Colorado Springs, CO
Netgear WNDR3700 V1 (firmware V220.127.116.11-dnsNA) connected to Zoom 5341 H (SW version 18.104.22.168pre5)
NB: for some reason, Firefox 13.0 had network.dns.disableIPv6 in about:config set to true, so IPv6 tests failed. Mozilla says this should be false by default. Took much time to find the problem!
