FIXME: didnt actually check mozilla's DNS traffic yet. Reproducible: Always Steps to Reproduce: 1. load some site w/ dynamic hostname 2. move the site to another IP and update the record (or wait until it will be done, i.e. on DIP-reconnect) 3. try to load this site again I've using such a dynamic hostname at www.dev.metux.de, its my workstation behind a DSL line w/ dynamic IP allocation and automatic reconnect once a day. Try to access my site, leave mozilla opened and try again 24h later.
Darin, could you look into this? Thanks. I'm not sure if this is an NSPR bug or a Necko bug.

fixed by bug 205726, for 1.6alpha... you should update mozilla, 1.5 is really old. note: the C library doesn't tell mozilla about the TTL, so it can't use that. however, since that patch, mozilla assumes a TTL of a few minutes (five, I think), and removes the entry from its cache. *** This bug has been marked as a duplicate of 162871 ***
