Configure your machine without any IPv6 routes and setup the firewall to 
reject IPv6 traffic. Squid will handle the rest automatically as long as 
ICMP is working properly.

Note that the error page you got shows the *last* destination to be 
tried and fail. All the others have to fail first - both IPv6 and IPv4.

So for this to show an IPv6 it means the site is IPv6-only or you 
configured "dns_v4_first on" so the last destination on Squids list was 
an IPv6 instead of an IPv4.
