Re: [IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEP Livermore, California
Your IPv4 address on the public Internet appears to be 24.
Your IPv6 address on the public Internet appears to be 2001:558::72c9
The World IPv6 Launch day is June 6th, 2012. Good news! Your current browser, on this computer and at this location, are expected to keep working after the Launch. [more info]
Congratulations! You appear to have both IPv4 and IPv6 Internet working. If a publisher publishes to IPv6, your browser will connect using IPv6. Your browser prefers IPv6 over IPv4 when given the choice (this is the expected outcome).
Your DNS server (possibly run by your ISP) appears to have IPv6 Internet access.
Your readiness scores
10/10 for your IPv4 stability and readiness, when publishers offer both IPv4 and IPv6
10/10 for your IPv6 stability and readiness, when publishers are forced to go IPv6 only
