what is 198.41.0.10 // j.root-servers.net

my firewall reports it blocked access to
198.41.0.10 // 198.41.0.1 // 198.41.0.4
from it's outer interface to port 53.

These are reported as j.root-servers.net,
a.root-servers.net at network-solutions.inc

anyone knows what that means?
is it necessary?

kind regards, christian

Port 53 is dns, and *.root-servers.net are the root dns.

You probably did not set an dns to forward queries to, thus using root servers.

thank you!

that makes sense to me ;-)
i gave the machines:
1.nameserver: inner nic of asl (= gateway)
2.nameserver: universities dns

aslbox dns activated, university dns given.
maybe it's denied from university dns because it doesn't know 192.168.1.250 (of course) ?

when i do nslookup on solarisbox i get such kind of message.

which asl-box ip is to use for dns-entry?

kind regards, christian
