Dear someone from Verisign, It looks from over here (and some other hosts I checked) that http://www.verisigninc.com/ is dead when using a host having iPv6 dual-stack. Some packets do come over, so the browser is not failing over into IPv4. Also the whois server for whois.nic.name is not working for IPv6 dual-stack hosts. The IPv6 part of the whois server claims that he is dead and so again failover to IPv4 is not going to happen. Contact me off-list if necessary. regards, Igor Ybema
