I have a friend who has a website, with DNS hosted on no-ip.
I tried to browse to his website today, but it didn't work.
Tried it from my work connection (vector) and it worked fine.

Tried to ping ns1.no-ip.com and it's a no go. Doesn't resolve an ip or anything.

I can browse directly to the IP's and ping them, just not the domain names.

If I change my DNS to google, then it all functions as expected.

Can anyone else on a snap VDSL connection try ping ns1.no-ip.com and see if it works?
