change DNS records?

Posted on 2006-05-22

I currently use Covad DSL service to connect to the Internet and am maxed out at 10,000 feet.
Covad also hosts my website and domain email,  
I am switching my Internet service to Verizon's FIOS service for my Internet connection but leaving the web and email hosting with Covad.  
Do I need to make any changes to the information at Network Solutions?
The ip of my website and email should stay the same if I stay with Covad for the hosting, correct?
I know my IP block will change when I switch to Verizon and I will have to make those changes on my firewall, but do I need to do anything else?

    If you keep Covads for hosting, your IP info won't change, so you won't need to change anything at Network Solutions.  The only reason why you would need to change the NetSol stuff is if your DNS servers change.  Other than that, you're right on the money... change your firewall and you're all set.

    Good luck!

    As SplinterCell5894 said, you'll be OK with your recrods (A, ptr, etc), owever, you may want to change the forwarder on your DNS server to point to the DNS servers of your new ISP.  Everything else will be OK.

    Ok.  So I don't change anything on Network Solutions but I change the DNS forwarder to Verizons DNS servers? Do I also put Verizon's DNS servers ip addresses in my firewall entry?

    Sounds like you've got it down.  Don't do anything at NetSol, but go ahead and change your DNS forwarder and firewall to Verizon.

    For clarification, you've got two different issues with DNS.  For lack of better terms, I'll call them "inbound resolution" and "outbound resolution".  The two are not really related.

    1. "Inbound Resolution" - This is where people are trying to connect to your stuff.  You have to have your domains registered with a domain registrar, such as Network Solutions (who I *always* recommend using), then you have to tell them what DNS servers you are using for your domain.  In this case, you're using the servers at Covads.  So, now when people try to connect to your web site, or send you mail, the find your DNS servers at Covads and get the right information and then connect to you.  As long as your Network Solutions stuff is good, then people can find you on the internet.

    2. "Outbound Resolution" - This is where you're trying to connect to other people's stuff on the internet.  These are the settings on your DNS server that jocasio123 is referring to and what you're talking about on your firewall.  These are the DNS servers that you use to find the web sites that you are going to.

    The thing to remember is that you can use any DNS servers for "outbound resolution" that you want... as long as they allow you to connect.  For the "inbound resolution" you HAVE to use the DNS servers that host your domain.
