Hi,
Have done a quick search of the Bliki and Forum, but forgive me if this has been discussed and I somehow missed it.
I'd like to do round robin DNS from the Rimu DNS system, but this doesn't seem possible.
More specifically:
- host1.mydomain.com has fixed IP
- host2.mydomain.com has dynamic IP and is updated using groovy Rimu Dyn DNS thing.
- host3.mydomain.com has another dynamic IP, updated as host2.
All hosts have content mirrored so they should work just find using round robin DNS. I'd like to setup a CNAME:
- something.some-other-domain.com ->
host1.mydomain.com,
host2.mydomain.com,
host3.mydomain.com
I think this is technically possible using some versions of BIND. Erm... whether it's a good practice or not, well - you tell me! ;)
Given that host2 & 3 can change their IPs at any time would rather keep things as above. Although again, it's technically possible to have a host update a list of IPs when it's IP changes (host2 knows it's the middle one, and to read the A entry and only update the middle IP address) but would rather not.
Of course, any other suggestions to balance traffic over hosts with dynamic IPs would also be appreciated. :)
Cheers,
Robin
