Post subject:  DNS Manager and related questions
Hello:

I have a few questions in regards to the DNS Manager, etc.

I have mydomain.info at Shared Hosting provider now.

I have mydomain2.info (temporary) pointing to the Linode I have been configuring as replacement.

I am getting ready to pull the switch to move mydomain.info to that Linode server.

Q: Can I have 2 entries in the DNS Manager both pointing to the same Linode server, or do I need to delete the temporary mydomain2.info first?

Q: If I make the Domain Name Server change to Linode at Hover for mydomain.info and for some reason there is an issue, can I change the A Record in the DNS Manager at Linode to point back to the IP of the old server (15 minute propagation time versus possibly longer if I change back at Hover)?


Also, on the server side (Ubuntu 13.10) this is what I have in the /etc/hosts file:

Code:
127.0.0.1       localhost
23.239.xx.xx    mydomain.info
23.239.xx.xx    www.mydomain.info
23.239.xx.xx    mydomain2.info
23.239.xx.xx    www.mydomain2.info

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters


I don't have any virtual hosts at this time, everything is in the /var/www/ directory that needs public access.

Q: Is this the best way to handle both domain names for this situation, or do I need to do anything different?

Q: Also, assuming I want to add IPV6 AAAA record to DNS Manager, I assume I would also need to add the IPV6 address(s) and domain names to the /etc/hosts file as well (may not really need to do this yet)?

Sorry for all the questions, most information I have searched for in regards to this shows Apache 2.2 information, and I am on Apache 2.4 in which some things have changed, and I have found conflicting information in a few places.

I am just trying to make the server change as seamless as possible.

Thanks for the help as always!

John
