All, Don't know if it'll help or if this is simply old news to most, but the whois systems (whois.internic.net/whois.crsnic.net) have AAAA records and happily answer TCP/43 requests w/ the usual blurb, but all the servers I've hit then fail to actually provide data and instead the whois client (Ubuntu 13.04) simply time-outs. sfrost@tamriel:/home/sfrost> whois -h 2001:503:5ae2:1060::74 networksolutions.com Whois Server Version 2.0 Domain names in the .com and .net domains can now be registered with many different competing registrars. Go to http://www.internic.net for detailed information. Timeout. Servers that I've tried so far (all IPv6 addresses I got through running 'host whois.crsnic.net'): 2001:503:5419:1060::74 2001:503:3227:1060::74 2001:503:6810:1060::74 2001:503:bfb0:1060::74 2001:500:30ff:1060::74 2001:503:7bbf:1060::74 2001:502:be98:1060::74 2001:502:8c25:1060::74 Anyone from NetSol care? It's not the end of the world, but it certainly is quite annoying.. Judging by some complaints on the 'net, looks to be a rather long-standing issue too (there's a Debian bug #683187 which mentions similar issues from nearly a year ago..). Thanks, Stephen
