I tried using those servers, and they didn't work. If I do an nslookup or dig through them, it's fine, but when I use them as the default nameservers in my network configuration, they seem to reject my requests.
Anyone know why?
- pyre 17y agoDon't know. I usually set them as the default DNS servers for my router to hand out through DHCP.
- thaumaturgy 17y agoTry `nslookup -vc [hostname]` after setting your name servers to the Level3 IP. Just a wild guess. I can't remember off the top of my head if nslookup or dig, when specifying an alternate server, use TCP or UDP. But, if it uses TCP for those, then it's possible that your ISP is blocking UDP DNS traffic that's not destined for their DNS servers. It wouldn't be the first time.
- akamaka 17y agoWeird. It works now, unlike the last time I checked. Something must have changed, but I don't know what.
