networksolutions.com also does not resolve on comcast or CL dns servers. It does resolve on google dns servers but it is not accessable.
This domain name has three name servers but all of them have the same IP address! % check-soa -i networksolutions.com ns1.netsol.com. 209.17.114.135: OK: 2014103001 (19 ms) ns2.netsol.com. 209.17.114.135: OK: 2014103001 (20 ms) ns3.netsol.com. 209.17.114.135: OK: 2014103001 (20 ms) So, any IP problem (routing, filtering, whatever) will take them down at the same time. What to add? It is Network Solutions. The gods themselves cannot make them professionnal.
COMCAST DNS SERVERS: DOES NOT WORK
server 75.75.76.76 Default Server: cdns02.comcast.net<http://cdns02.comcast.net/> Address: 75.75.76.76
By the way, nslookup is a poor DNS debugging tool.
