DNS changes on Comcast

[Thomas Taylor]

Hi All:

Got the following email from Comcast and I'm not sure how to proceed;

"This will be our final courtesy e-mail to remind you that your PC must be 
configured for dynamic DNS communication by March 12, 2006.   As you may 
recall, we recently updated the domain name server ("DNS") components in our 
network to help ensure that we continue to deliver the high quality service 
you expect from Comcast."

My gateway (192.168.0.1) is a netgear WGT624 wireless router on a small home 
network.  I'm only using the lan portion now as I no longer have a working 
laptop.

The router is set up for dynamic DNS and addressing through nat from the cable 
modem.  On the computer side I use static addresses and have always assigned 
the DNS addresses Comcast gave me several years ago.

My question is, do I need to change the DNS settings of each of my computers 
or will the dynamic DNS on the router take care of this.  I haven't seen this 
discussed on any of the lists I monitor nor seen anything by googling.

Thanks,
Tom

That should be fine as the router is getting its outside address from 
their dhcp servers already. So you should be able to continue as you 
are.

If you used your DNS settings from years ago for the static setting you
do have to change them to the new DNS server addresses once they take
effect. This is only changed on the computers you have static on. Like
Gene mentioned before the router should be fine.

This happened to be before!! :)

I have not used that specific router, but if it is like the others I
have used, then you can set the router address as your DNS server,
and it will forward to the dynamically assigned name servers that it
gets via DHCP. That way, you do not have to change anything when
your ISP changes the name servers. It may also have an added benefit
of caching DNS for you as well.

Be aware that you don't have to use the DNS servers provided by 
Comcast. A quick google will reveal lots of public dns servers that 
perform better than the Comcast DNS servers.

This being the Fedora list, you also have the option of using your own. 
Just "yum install caching-nameserver" and edit your resolv.conf to point to 
127.0.0.1. You'll need to edit the line in your interface config to prevent 
the DHCP client from overwriting resolv.conf. (Is there a GUI to change 
that setting? I always do it with a text editor.) Looking at 
/sbin/dhclient-script, it looks like you need "PEERDNS=no" in your 
ifcfg-eth0 script.

Thanks to all those who responded to this question.  After looking at your 
solutions, I have reached the conclussion that this network may have a faulty 
operator/user assembly.  The memory components seem not to be working 
properly some of the time.  Hmm, wonder where I could get some replacement 
core memory to fix that, SIGH.

Things can be so obvious in hindsight.

Gene, maybe I should take you up on some of that West Virginia coffee!

Thanks,
Tom

Wet ram?  When you locate a good dependable supply, lemme know too.  At 
71, mine is showing signs of failure from time to time.

Chuckle, knowing well that coffee is a buck plus almost anyplace else 
I've gone in the last 5 years, I figured that would get some attention.  
I really like the Go-Mart policy though, get one of their small (12 oz 
I think) cups, empty it, take it back in and the refill is only 35 
cents.  Or was the last time I did that.

But its going to be quite a drive to do that. I'd look it up on one of 
the trip planner sites but I'm too lazy this morning, haven't had my 
tea (green even) yet.  SWAG its about 3k miles one way?
