Now issue is client need same IP on both server as his webapplication make request to another server and if I use DNS failover, then backup server will have new IP and it won't work for the client.

You can certainly setup cPanel and it will handle the DNS for you. You'd still be able to do all of those things with dns.he.net or CloudFlare DNS.

If you aren't using a panel/aren't hosting many domains you should be using offsite DNS, it will be far more reliable then anything you setup and there's not to configure.

So I just changed VPS hosts and the one I changed to doesn't have their own nameservers for me to point my domain to. They recommended I follow this tutorial for installing a DNS server in CentOS (ht

If anyone is trying to figure out where to go I have done a write up covering most of the top free ddns services.

You can try our dynamic DNS - we have clients for both MS Windows (beta version) and Linux (bash based)

Dyn DNS clients are not of much use to me if they don't run as a service.

Again, DuckDNS. Amazing Ec2 based service.

Doesn't look like the namescheap client runs as a service and I don't feel like farting around trying to make it do that. Are there any free or nearly free dyn DNS clients that run as a service?

@sman: Yes and Yes. They did have a DDoS February of this year that interfered with their "v2" DNS for over 3 hours, but otherwise it works well.

There is tons of different awesome providers who sharing their DNS.

Oh well, no big loss. As expected; aren't they the ones who gobbled up a bunch of free providers like EditDNS, EveryDNS, TZO, etc ....... to now kill or curtail the free services?

What DNS do you use?

If you use any other DNS server that's not on your own server then yes it will reduce server load on memory and CPU. Cloudflare is an excellent choice

dns.he.net is free and has dynamic dns functionality. Namecheap's free dns also has similar functionality. You have to have your own domain, though.

* Use specialized VMs for special activities, such as a totally open source system and with all traffic encrypted and passed through Tor, this way you will greatly reduce the risk of leaking DNS traff
