It seems like the options are: -Use the elastic IP address (con: security group rules get thrown out the window) -Use the internal IP address (con: changes if the DNS server ever reboots) Any advice? How do you maintain the nameserver IP’s in the resolv.conf’s on servers using your internal DNS? It seems like the options are:

-Use the elastic IP address (con: security group rules get thrown out the window)
-Use the internal IP address (con: changes if the DNS server ever reboots)

Any advice?

"Where a.a.a.a and b.b.b.b are name servers in the us-east-1 region and c.c.c.c and d.d.d.d are in the eu-west-1 region." Correct.

“Where a.a.a.a and b.b.b.b are name servers in the us-east-1 region and c.c.c.c and d.d.d.d are in the eu-west-1 region.”

In the above post you have:

searchdomain ez.domain.int
nameserver c.c.c.c

The nameserver value “c.c.c.c” is that the internal IP for the EC2 instance running BIND?

You should set up your clients inside EC2 to utilize the DNS service inside EC2, and the domain should be configured to point to the DNS service running outside EC2 so that clients outside EC2 will see the public IPs. Note that clients running inside EC2 whose DNS resolution you do not control (for example, another EC2 user’s client) will be referred to the public IPs. Jeff Roberts offers some great practical suggestions for running your own DNS inside EC2.
