Okay, so for those of you not aware, to essentially make it simple, AWS will change the IP's of their dns records on the fly. They do however, give you a a long load balanced FQDN to compensate if you will.
To better explain. I have a site www.NOTaREALsite.com.
You ping this site and you get an IP. This IP is publicly delivered by AWS. This IP can and does change on the fly, however if you nslookup the site you get a long ELB (elastic load balancer)
somerandomtstring1234556666.us-east-1.elb.amazonaws.com
Now if you look that long ELB up you get all the IP's that could be.
how does this all play into my question?
Well I have a bunch of server that unfortunately right now are band aiding a problem by adding the DNS entry by static host list. Because the IP changes, well that Static Host list becomes useless until we edit it with the new IP.
My question is? How can I get these servers to look for the "LONG ELB" when trying to go to NOTaREALsite.com?
How can I make DNS look to that ELB for that NOTaREALsite.com lookup?
