On our SMTP hosting provider, they have 'redundant' DNS entries for the same FQDN:
[C:\]nslookup server1.inboundmx.com
Server: abc.xyz.local
Address: 192.168.253.254
Non-authoritative answer:
Name: server1.inboundmx.com
Addresses: 216.82.253.99
216.82.255.3
216.82.242.99
216.82.242.115
216.82.250.115
My question to the group - can this general idea be used to create 'backup' web
servers?
i.e.:
www.mycorp.com<http://www.mycorp.com> 1.2.3.4
www.mycorp.com<http://www.mycorp.com> 4.5.6.7
The way inboundMX described it, it was more of a load balancing thing. I don't
think a client stack will know to query DNS 'again' if the first IP address was
down.
Is this kosher?
I couldn't see a way on the big registrars to have multiple "A" records anyway,
so it may not be possible, but I thought I'd check.
