You seem hung up on the idea that pkg.freebsd.org should resolve to a list of IP addresses. It doesn't and for very good reasons. Admittedly, using eg. 'http://' as the URL scheme for PACKAGESITE URLs was an error -- it contravenes RFC 2616 -- which is why we will be switching to a new 'pkg+http://' (or 'pkg+https://', 'pkg+ftp://', etc.) set of URL schemes with pkg-1.2.x There certainly are all of the necessary A and AAAA records in the DNS for the real servers that host the repositories. If I understand what you're complaining about is that you see behavious like the following: * You download package foo-1.2.3.txz from pkg.freebsd.org * Internally, that gets resolved to an HTTP request to eg. pkg0.isc.freebsd.org * Your web proxy caches this package * On another host, you also want to download foo-1.2.3.txz * This time the SRV record gets resolved to a different mirror, say pkg1.nyi.freebsd.org * Your proxy has no way of knowing that foo-1.2.3.txz from pkg1.nyi is exactly the same file as foo-1.2.3.txz from pkg0.isc so it downloads the whole package all over again. Yes, this is certainly undesirable behaviour. I need to run some tests to determine if this is actually what does happen in practice. If so, I've an idea about how this problem might be addressed, but it will require some changes to the repository configuration. In the mean time, I suggest just choosing which ever of the pkg.freebsd.org repositories is closest to you and using it directly -- e= g. cat <<EOF > /usr/local/etc/pkg/repos/myrepo.conf pkg0.isc { url: http://pkg0.isc.freebsd.org/${ABI}/latest enabled: yes mirror_type: none } EOF Obviously, substitute which ever one of pkg0.isc.freebsd.org (US West) pkg1.nyi.freebsd.org (US East) pkg0.bme.freebsd.org (Europe) is appropriate. And be prepared to deal with that specific mirror being down or replaced by some other server. > Alternatively, running an HTTP-redirection service on a host named > pkg.freebsd.org would offer as much flexibility as the SRV records, if > not more.

This would entail significantly more administrative effort and hardware requirement to maintain and keep consistent in the specific case of pkg.freebsd.org which is exactly why the SRV mirror type was selected.
