Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

DNS servers that are pre-configured on EC2 instances seem to be only: 172.16.0.23

Does anyone know if thats a dedicated DNS VIP for a specific region? Should we add more DNS servers in for fault tolerance?

I've never felt the need for anything else.

ec2-user@ip-10-112-39-42:~$ cat /etc/resolv.conf 
nameserver 172.16.0.23
domain ec2.internal
search ec2.internal
ec2-user@ip-10-112-39-42:~$

Feel free to change it if you want, though be aware that external DNS servers won't be able to resolve ec2.internal addresses.
