(RFC 6540, also known as BCP 177). The option available to make Squid prefer IPv4 over IPv6 is "dns_v4_first on" which you found. With that Squid is already trying all available IPv4 connections to the destination domain before its tries any IPv6 ones. The reported "failed" IP was simply the last to be tried out of the full set. Possibly Squid was instructed to connect to exactly that IPv6 address and no DNS is taking place at all. Either way the entire domain/network is unreachable with the information in the URL given. If you get IPv6 working you may be able to access those URLs. That can be as simple as installing miredo software, or setting up a 6to4 tunnel to 192.88.99.1, or both on the Squid machine.
