Looking for DNS Service.

ContemptX · #1 12-11-2007, 09:52 AM

Unsure if this is the right place for this post but will continue you anyway.

I have a multi-server setup DB, Web, Media etc..

Unsure if this is the right way to go about it but I setup for example:

Web Server:
bleach-network.com

DNS
m1 - A - Media 1 IP
m2 - A - Media 2 IP

Media 1:
m1.bleach-network.com

Media2:
m2.bleach-network.com

Now this works and everything works fine.

BUT If the Web Server goes down

m1. & m2. no longer resolve as they are setup on the web server

So im looking for a DNS Service where I can setup these so if a server does go down the DNS still resolves correctly.

OR, do I not need a DNS service? and im just setting up things a little wrong?

Thanks In Advance

Either you can go for a third party dns service or you can buy a reseller account somewhere else and setup dns servers and zones for your domains configured on the webserver in this reseller account. You can set IN A address in the zone file of the domain there pointing to your webserver IP. In this case, when your webserver goes down dns server will be up.

Are Web Server and Media 1 and 2 on the same machine? If so, it's pointless as everything will go down together. But if Web Server, Media 1 and 2 are all on different machine then it's do-able. Of course DNS cannot be on the same machine as any of them.

Web Server, Media 1 & Media 2 are all seperate servers.

Why not?

ContemptX: Are you looking for some kind of failover or just a more reliable DNS service? Since you have 3 physical servers already a perfectly reasonable solution for you would be to run DNS on all 3 (particularly if they're in different locations). If you do this though you'll need to set them up to synchronize, most likely by having the media servers work as slaves to the web server. Alternatively you can just use an external DNS service, which is cheap and easy.

If you want failover it's still doable on your own servers but tricky - the external DNS service is a particularly attractive option in this case.

You should probably go with one of the more reasonable managed dns services. That way you get all those cpu cycles off your machine and you benefit from a service with good uptime.

As long as you are not using short ttl's or failover services, their prices can't be beat. You can then dedicate the boxes to more productive uses.
