Thank you…this is very useful information; I thought TTL could only be specified on a per-zone basis, not per-host.
not even per-host. Different RR types for the same host can have different TTL.
mail 1m IN A xxx.xxx.xxx.52; dhbex1 mail 1m IN A xxx.xxx.xxx.54; dhbex2
mail 1d IN TXT "v=spf1 a -all" mail 1h IN MX 0 mail etc. Only same RR types MUST have same value so e.g.: mail 1m IN A xxx.xxx.xxx.52; dhbex1 mail 2m IN A xxx.xxx.xxx.54; dhbex2 would be incorrect and server will choose one of those to implement for all RRs (see rfc 2182 section 5.2) -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
