<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">share/debian-edu-config/squid.conf: Prefer DNSv4 lookups over DNSv6. Debian Edu does not yet fully support IPv6 and many schools still use IPv4 primarily. This gives a great performance boost to squid installations if IPv6 internet is not fully available for whatever reason. (Closes: #1006375).
