Package: whois

Severity: normal

For the last few months replies from the whois servers at crsnic.net have been
spotty. Today I got annoyed enough to diagnose it.

Often the requests will fail like this:

-----------
$ whois nytimes.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.

I found that the problem stems from IPv6 servers that don't respond. These IP 
addresses are resolved for whois.crsnic.net:

-----------
$ host -t aaaa whois.internic.net
whois.internic.net has IPv6 address 2001:501:8a29:1060::74
whois.internic.net has IPv6 address 2001:502:8c25:1060::74
whois.internic.net has IPv6 address 2001:502:be98:1060::74
whois.internic.net has IPv6 address 2001:503:3227:1060::74
whois.internic.net has IPv6 address 2001:503:4872:1060::74
whois.internic.net has IPv6 address 2001:503:5ae2:1060::74
whois.internic.net has IPv6 address 2001:503:7bbf:1060::74
whois.internic.net has IPv6 address 2001:503:91ef:1060::74
whois.internic.net has IPv6 address 2001:503:bfb0:1060::74
whois.internic.net has IPv6 address 2001:503:f3da:1060::74
whois.internic.net has IPv6 address 2001:503:ff39:1060::74

Of the IPv6 servers, these don't respond at all:
2001:502:8c25:1060::74
2001:502:be98:1060::74
2001:503:4872:1060::74
2001:503:7bbf:1060::74
2001:503:f3da:1060::74
2001:503:ff39:1060::74

These servers respond but time out before giving the information requested:
2001:501:8a29:1060::74
2001:503:5ae2:1060::74
2001:503:91ef:1060::74
2001:503:bfb0:1060::74

Only one of the IPv6 servers responded and gave the correct info:
2001:503:3227:1060::74

These servers aren't even listening on port 43:
2001:502:8c25:1060::74
2001:502:be98:1060::74
2001:503:4872:1060::74
2001:503:7bbf:1060::74
2001:503:f3da:1060::74

While the problem is obviously caused by issues with the remote servers, it
would be good if whois could deal with broken servers like these more
gracefully (though I don't know how this could best be done).

As a temporary measure I've added the working servers to my dnsmasq config:

-----
address=/whois.crsnic.net/199.7.57.74
address=/whois.crsnic.net/2001:503:3227:1060::74
