Hello, I have recently switched from having a dynamic IP address and using a DNS service like zoneedit and dyndns to having a static IP address. How do I stop having to use these DNS services and use my own? I tried changing the DNS servers at my registrar but it won't accept my server. TIA

IIRC, this must be approved (or rather not denied) by your ISP. Then you can set up your name server to provide DNS services. Keep in mind that you must have a minimum of 2 name servers to handle DNS. Some ISPs will provide secondary or slave DNS services included in your service, others will provide it for a cost, and others won't offer it at all. Of course you could also contract elsewhere for secondary DNS services. Best practice is to not have both of your nameservers on the same class C network. HTH, Barry
1. Build a primary DNS centos 4.3 server, and make the required efforts to configure it properly. Do the required effort to have a secondary nameserver, like using granitecanyon or other similar service if you don't have the physical hardware just yet. I use Bind for my dns servers. 2. Ping it on it's static IP from a remote machine to assure it can be seen, specifically on port 53. You can usually block all of the other ports with your firewall. 3. Aim your registrar/ domain name at this new IP as the "primary nameserver". I find that using web forms are less cooperative than contacting the registrar's tech support by phone and having them make the change. Web forms have error checking, sometimes accurate, sometimes false positives. Either way, the human can say things like "i'm not seeing that on ping or nslookup/dig the same as you, let me check into that". 4. Audit your entire setup, bring it online. Try using weekends for testing. 5. Buy a good DNS book, or download one of the FAQ's, join mailing list for bind or other technology, and use programs like tcpdump and ngrep for testing. I like ./ngrep '' port 53 or similar because I can see the server start to contact root servers as it propagates. maybe i'll make a basic howto "Installation & Configuration of Bind on centos 4.3" and submit it. -karlski> Hello, > > I have recently switched from having a dynamic IP address and using a DNS > service like zoneedit and dyndns to having a static IP address. > > How do I stop having to use these DNS services and use my own?

I ask as mine does, but only forward, but my ISP supplies reverse DNS. Rob
Hi There
Been using the BQ Cent OS on 2 servers with DNS
I have 3 other DNS's ... 5 all told
I may add a 6 in the next few weeks
DNS to me is the easy part.....
I just had to change 2 DNS IP's because
my co lo provider changed
Backbone providers.... Fun..Fun...
Be sure you have the IP/Name in your registrar
and you need 2 DNS's as a minimum
and you should have dns's on different
classes of IP address...
I have DNS's on Cable Modems, ADSL
and a T3....
You could run a DNS from a dial up because the
data needed is in the bytes size...
Once a DNS is working ...it will run by it's self
I have even used TreeWalk DNS if you do not mind the
use of notepad to set it up....
Drawback..... If you get someone PO at you they can
take you off the net by doing a DDOS attack against
your DNS's and get your provider PO at you....
But they could flood your pipe just by flooding your
web server.

My 2 cents: Never get caught between 2 Tier 1 ISP's in a pissing match!!
The Net will loose every time!!!

Hello,
I have recently switched from having a dynamic IP address and using a DNS
service like zoneedit and dyndns to having a static IP address.
How do I stop having to use these DNS services and use my own? I tried
changing the DNS servers at my registrar but it won't accept my server.
TIA
