No. There's not a lot of data in a record file, and it's generally only your own authoritative data that's stored on disc (unless you configure otherwise). Looked-up records are cached in RAM. Here's an example record for an entire domain: -------- begin example ------- $TTL 86400 @ IN SOA localhost root.lan.example.com ( 42 ; serial 3H ; refresh 15M ; retry 1W ; expiry 1D ) ; minimum IN NS localhost A 192.168.1.2 MX 1 mail.lan.example.com. andy A 192.168.1.10 caan CNAME roar clock CNAME time default CNAME www finger CNAME server ftp CNAME server gateway CNAME router gales A 192.168.1.2 gonzo A 192.168.1.11 hear A 192.168.1.3 imap CNAME mail jabber CNAME server -------- end example -------- The last 12 lines are the records for particular hosts in that domain, and you can see that it's only a tiny bit of data per host. -- (Currently testing FC5, but still running FC4, if that's important.) Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
