You need to go to your domain registar and register "both" nameservers to your VPS's IP. You should be able to find a tutorial by googleing "{your domain registar} custom nameservers tutorial" without the quotes.
No you don't. It's a waste of IPs if they are both on the same server and not needed for SSL or something else. You would need 3 VPSs in different datacenters if you were following RFC 2182. 2 IPs on the same VPS does not add ANY redundancy.

How does 2 IPs on THE SAME VPS add anything to your redundancy? Only multiple servers in multiple locations would provide additional redundancy.
Where did I say that it did?
In order to correctly set up your DNS, you need at least TWO dedicated IP addresses registered with TWO different nameservers pointed to TWO different machines on TWO different subnets... minimum.
If you want to set up your DNS half assed, then yeah register two different nameservers with your domain registrar, point them to a single IP on one machine and then create a single point of failure.

Yes, it will work.
Yup. And considering how cheap you can find 512MB-1GB VPS these days it would be sad not to setup a DNS cluster.

I run my cPanel DNS Only on 128mb guaranteed/256 mb burst VPSs (these can be found for $15 a year.) 1GB is overkill for DNS.
You know what's really sad is that 95% of the hosts on this forum have DNS that is set up incorrectly or have single points of failure. You question them on it and they act like you're the fool for pointing out their faults, or they play ignorant. Oh well.
That's nice and all, but I was just making an observation. I don't really care if you use 64MB or 10GB of RAM for a DNS server.
Yeah, I was pretty surprised when I read the thread Schmarvin made and discovered that he had no PTR records setup; especially since he is a paid web host. I was even more surprised to learn he only allowed 25 emails a hour and said anyone having problems with his mail server should use google apps.
The kicker for me was he thought reverse DNS allowed for more spam.
I'm not really trying to start a flame war here or cast a bad light on people, but some of these web hosts really need to get better educated.
I run DNS checks on folks around here just to see who has their DNS set up correctly and who doesn't. You'd be surprised at the results. Almost all of these "hosts" on here have some kind of DNS problems or have DNS that are set up incorrectly. That's no exaggeration either. The average customer wouldn't know any different, and apparently these kiddie hosts do not either.
If the DNS server fails, wouldn't apache fail as well under most circumstances? I've only had my DNS server fail on its own once, and that was completely my fault. Having another DNS server wouldn't help much, unless you had a backup server running as well in a completely different data center, right? But then forums and blogs would be messed up from wrong posts. How many servers should the OP purchase to run his personal site?
Because if one IP gets attacked by DDoS, then the other is still available. As well as your secondary nameserver, if you had one.
That's how I was able to make backups of everything.Because if one IP gets attacked by DDoS, then the other is still available. As well as your secondary nameserver, if you had one.
That's a joke right? A DDoS would take out the entire box under most circumstances making a second IP irrelevant. By the time you null routed the IP the DDoS was hitting the damage would have already been done.
Really? I can still access my server fine. As by my provider, it was a 600mbps attack which is still going on and hitting the one IP they have null routed. I can still access my server and files easily though. So I just poked a hole in your theory.
When you null route the IP the DDoS is hitting obviously the rest of the server will stay online. Were you still able to access the server when the IP wasn't null routed?
