Where will be domain name redirected ?

[Luke]

What would happened if I set DNS to:

ns1.fastpark.net
ns1.sedoparking.com

instead of:
ns1.fastpark.net
ns2.fastpark.net

or

ns1.sedoparking.com
ns2.sedoparking.com

Where will be domain name redirected : sedo or ND?

ns1.fastpark.net
ns1.sedoparking.com

This first option means that 99% of the time your website will be redirected to fastpark and only if that first DNS server is unavailable to sedo.

ns1.sedoparking.com
ns2.sedoparking.com

Here your domain will always be redirected to Sedo.

It's my understanding that it is good practice to have nameservers on different networks, right?

So the chances that both of a company's nameservers goes down is slim - but something just occured to me - many registrars have several fields for you to add even more backup nameservers.

So it wouldn't be such a bad idea to add in a second PPC company for the 3rd and 4th nameserver, would it? - as a failsafe in the odd chance that the first company disappears...

r3dbaron: The order of the nameservers does not have anything to do with the order they are queried in - most nameservers trying to resolve one of your domains will just pick one nameserver at random - at least that would be the expected behaviour.

So if you are trying to achieve a 50/50 traffic split between two parking programs, I would not recommend this method, since it's not going to split the traffic exactly at 50%. It will always depend on where the user is coming from and what their upstream DNS might have cached.

If your parking providers allow you to use URL forwarding, you can use a service such as DomainManager.com to split traffic between two destinations.

Another reason to be careful which DNS to list is that some parking providers might also check the zonefiles or try to resolve your names in order to see if your name is actually pointing to them.

RazorNF is right though that the nameservers ideally should be located in different subnet - it is surprising how few people stick to that rule. The question here might be what Luke's goal is - additional redundancy or to rotate between programs.

Hope this helps,
