I'm looking at the spec for Via: processing. RFC 3261 clearly shows that a Via: line can contain DNS names, as well as textual representations of network addresses.
How many products actually implement support for resolving DNS names provided in Via: lines? This seems... well, it seems unnecessary, potentially insecure (allowing for easy DDoS and potentially amplification attacks), and just a general nuisance. Is this kind of thing ever actually used for a good purpose? Does any product do anything *but* just put real network addresses in Via: lines in requests? I'm not trying to stir up any controversy over this. I just want to clearly understand the spec, the motivations behind the spec, and the reality of implementations. -- arlie _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
