As I understood the rules of good Domain Administration, everything that is publicly visible in your network needs to have an MX record. But with this scheme you can't give cvsup.freebsd.org an MX record, because pointing an MX at a CNAME violates the RFC. Personally, I would much prefer the CPAN solution of a program that takes the IP address of the query source, and then using knowledge of what IP addresses are generally located where in the world (available via the whois maps in the various regions, which could presumably be imported and stored locally), returns a short list of addresses in the preferred order. For those networks where multiple addresses may have equal "cost", it can then randomize for load balancing purposes. It requires either a hacked nameserver program for this one zone, or the code to handle this has to be incorporated into cvsup itself, so that you distribute the logic and CPU processing time to all the clients. -- These are my opinions and should not be taken as official Skynet policy _________________________________________________________________________ |o| Brad Knowles, <blk@skynet.be> Belgacom Skynet NV/SA |o| |o| Systems Architect, Mail/News/FTP/Proxy Admin Rue Col.
