Determining DNS Servers?

[r00fer]

I currently have a Netgear RT314 router serving up dynamic IPs to my network and am planning on changing to static IPs. Is there any way to find out what DNS servers I am connecting to? My ISP is Verizon (DSL) and can't find any info on their website about which DNS servers I connect to.

Thanks in advance...

If you go into the routers setup page (usually via a webpage/telnet) there should be a status page that will tell you your public IP, DNS, Gateway and subnet mask

It only shows WAN IP and WAN IP Subnet Mask. Is there any other way? Or am I overlooking something?

Yes, on a computer that still as DHCP enable
go to start
run
type: comand

when the window opens, type: ipconfig /all

That will give you your DNS servers (as well as IP addy, gateway, etc)

You can also do an nslookup, but the ipconfig /all is much easier for ya!

Do I need to change from static to dynamic before I run 'ipconfig /all'? Because w/o changing it, the DNS server shows the router IP as the DNS server...

Are these them? 151.196.0.38 151.196.0.39

Hopefully this helps: http://www.broadbandreports.com/faq/1591

If not, use 142.77.1.5 for the time being.

I did a quick nslookup for verizon.com

Try these:

192.76.85.133 (that is vzdns01.verizon.com)
198.23.5.148 (that is DNS2.verizon.com)

these appear to be mail servers...would they double as DNS servers?

also, thanks for the link, i'll be lloking into some of those?

It is common practice for those to stricly be the authortative name servers, not caching name servers (ones that verizon clients would use in the IP settings).

So, how to find out then (about the authoratative vs. non that is)?

Is there anything like http://www.whatismyipaddress.com for dns servers?

temporarily hook one computer directly to the modem. Leave settings at " obtain settings automatically". Get connection going by a reboot, or ipconfig /release_all, renew_all.
Type Ipconfig /all
You will have your dns servers now.

that was my first thought...but it would take some work getting a temp computer into the server room...I was hoping for an easier solution...

my experience with nslookup: It reveals your primary DNS server in the first line, not the authoritative. It is labeled as ns (blahblah) ( your_isp_ here).
That won' help you with the secondary, but at least you'll have one.
try nslookup google.com , for instance. you should get a name on your nameserver associated in some way to your ISP.

4.2.2.1/4.2.2.2 They're fast (~16ms from San Diego) owned by a company owned by verizon sadly though :/ Down with verizon! 😛
