Routers not recognizing DNS changes
I am a web developer with matching R6260 routers at both my home and office. Both connected to the same ISP. In the past week I have made 3 changes to my client websites - 2 nameservers changes,...

Will it clear it up? Unknown but its worth a shot.
Its pretty easy to switch it back if it doesn't.
Again, if you have ipv6 enabled, check that as well.
What modem/gateway is it connected to?
You can also make a backup if you think it might corrupt something.

Thank you for the reply.
I'm reaching out to a friend who is on the same ISP, but obviously not using my routers, to see what result he gets.
Here is what I get on an NSLOOKUP, querying for the domain by itself (192.168.1.1), my ISP's DNS, and 8.8.8.8. The old IP of the website begins with 216, and the new/correct IP begins with 199.
C:\Users\matt>nslookup
Default Server: www.routerlogin.com
Address: 192.168.1.1
> websiteinquestion.com
Server: www.routerlogin.com
Address: 192.168.1.1
Non-authoritative answer:

Is it possible that while my ISP is receiving the correct IP, it isn't providing it to me?

Just heard back from my friend who has the same IP. He got the new website. So it appears as though the ISP is properly sending incoming traffic to the right place.
How might I get my local router(s) at 192.168.1.1 to send me to the right place?
I guess I can just wait another day or two, but especially since I'm the one administering the DNS changes it would be nice to be able to verify propagation locally.

What modem/gateway are you using?
Did you try changing the dns? Try changing it and then changing it back.
and check your ipv6 settings as well

Thank you again.
I'm attaching a screenshot of my router settings. Is the box I've drawn for DNS Address what you're referring to? Right now it's set to "Get Automatically from ISP".
If I set Primary DNS to 8.8.8.8 or 1.1.1.1, that will clear this up? I want to double-check before potentially making the wrong move.
Thanks!
