Dynamic DNS with Static IP Address on WinXP/Vista?

Hi,

Is it possible for Windows XP/Vista to be configured using dynamic DNS addresses but static IP addresses?

The guy on the phone at comcast just told me he does it at home but as I told him, when I try to assign an IP address statically, I can't assign the DNS address dynamically. The option to do so greys out as soon as I tell it to let me specify the regular IP address and it makes me type in the dynamic DNS.

I know I've accomplished setting it this way once before but 2 things. I don't remember how, and it told me my network settings were incomplete or something like that.

I'm looking around on the internet for the answer to this as well. I just wanted to see if anyone had a quick "yes or no", and how here first since this place is a treasure trove of information.

Thanks in advance,
Joe
 
You are talking about Internal or external IPs.

You can not decide on your own to use external Static IP address, it depends on your contract.
 
if you're using a static ip address (aka no dhcp) where do you expect to dynamically learn DNS servers from?

either go back to DHCP, learn your ISP's DNS servers, write them down and manually type them in, or just 4.2.2.2.
 
Jlazzaro, that is why I was asking. I was

As far as I know that is the only way to do it and that is how I got my dns servers the first time I got them but the guy at comcast says he does what I was asking at home on his XP machine. So my expectation was that there was some sort of hybrid mode that I didn't know about. I make it a point to tell myself that I don't know everything 🙂 .
 
Yeah. I was looking at my linksys setup and I can't figure out where that is if it exists at all. I think mine is called the WRT54G. Its pretty popular but from what I hear it is somewhat gimped in its capacity to do certain things.

the stock firmware doesnt allow for this

dd-wrt does, i havent used tomato, but id guess it probably does as well.
i use dd wrt at home and reserve addresses based on MAC addresses.
 
Thanks. I'll look into that. Changing the firmware to some non linksys version voids the warranty though, right? Would I be able to install the real linksys firmware back if there is a problem?

I'm not disputing what you're saying and I probably will use the dd-wrt, but I just want to make sure I know about the "consequences" if any.
 
Why do you need "DNS address dynamically"?

When using a Router the internal DNS is Router's core IP, it does Not change.

If a number does Not change there is No value to dynamic setting.


Are you sure that you are at the top of the Network terms, or your are confusing Internal and External IP settings.

If you want an Internal static IP assign one that is not within the Router's DHCP range, and in the DNS put 192.168.0.1 or whatever is the core IP of your Router.
 
The DNS addresses do change. I understand the terminology as the terminology really isn't that hard. None of this is really that hard to understand. It was just a question of knowing whether or not I can do what I was asking or any alternatives.

But I did learn something. I didn't realize that I can specify the actual router as the DNS server. That is awesome and thanks for the information. That completely solved my problem and works fine. It actually looks like the web pages load faster than they used to.
 
IP address: local IP you want to assign to PC
Subnet mask: 255.255.255.0
Default gateway: local IP address of router

Preferred DNS server: local IP address of modem
Alternate DNS server: blank

Problem solved.
