Non-authoritative answer:
Name: www.llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.co.uk
Address: 194.42.244.17

Netscape through Squid 2.2.STABLE4:

  Unable to determine IP address from host name for \
    www.llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.c

Note, the domain name is truncated ("o.uk" is missing); clearly "dnsserver"
can resolve the address (above) but Squid can't store a host name that long.

The truncated length above is 64 characters; according to ./include/util.h,
Squid should permit a maximum host name length of 128 characters, or the
system default (whichever is greater). On my system (Solaris 2.5.1) the
setting of MAXHOSTNAMELEN is 256. Hey, look at that - it's also defined in
./src/squid.h...

Cheers..
