ext.nic.cz


DNS delegation of ext.nic.cz updated:

Delegation

stepqueryauthservers
1ext.nic.cz..(g,k,d,l,e,m,j,i,f,b,h,c,a).root-servers.net.
2ext.nic.cz.cz.(c,b,d,a).ns.nic.cz.
We pick g.root-servers.net, one of the 13 root servers (1), and ask it about ext.nic.cz and learn that cz is delegated to four name servers (2), so we ask c.ns.nic.cz and get the following answer:
