Please be aware of the fact that I don't think that DNS is the correct tool to distribute files but for distributing something like a serial number it fits perfectly. The actual download of the data has to be done outside of the DNS system. > Also I was worried > about the fact that DNS servers usually got traffic for updates from > peers and client/server lookups, not spreading files...that would boost > their hits and bandwidth. I am afraid this is a missunderstanding as I am not advocating to distribute files via the dns but only a serial number. > vocalizing them or not...and they'll hopefully get an education from > the answers I get as the result of my chiming in :-) I think this is totally fine :-) > was supposed to.

In short: Using DNS for spreading _small_ pieces of information which typically have some reasonable TTL (time to live) and which can deal with the loose coherency of DNS is totally fine. Abusing the DNS to directly transfer files etc is not appropriate as the DNS infrastructure is not ready for such kind of "abuse". Regards, -- martin Dipl.-Phys.
