a general question: so i have this server handling some domains as
primary DNS, as well as being their web- and mailserver. another domain
does slaving and secondary MX, but because i don't want load-balancing
on DNS RR basis for webservices, and because HTTP can't deal with
secondary servers, webpages are stuck on that server only.
i have some 17 DNS servers under my control, so i am always tempted to
configure 4 DNS servers for each domain, that is, in addition to the two
main servers described above, i usually add two other ones out of the
pool of the remaining 15 to the WHOIS data and NS record of the zone
data.
however, this being an extra administrative burden, and me currently in
the process of moving to another registrar, i started questioning the
point of the additional two. assume the main server as well as it's mail
backup (the second server) both go down, then what's the point of being
able to resolve the zone data? i guess negative TTL, but is there
another reason? after all, what use is it to me to be able to resolve
e.g. metrosophia.com to its IP, if the IP and the backup MX are down?
i'd appreciate any comments.
