In my home network I have a couple of Windows based PCs that have no known issues with DNS but with my OSX iMac I have problems resolving a couple of random domains. Some domains that I have problems with are:
Besides looking at the /etc/hosts file (which I think is fine) what should I check on the iMac for problems associated with DNS or what tools should I used to help diagnose the issue that I am facing?
Using the dig command I get:
; <<>> DiG 9.4.3-P3 <<>> @18.104.22.168 www.nationalshoppingservice.com ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 3468 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;www.nationalshoppingservice.com.

After trying some of the suggestions I believe DNS is the wrong problem ... when I did a ping of www.nationalshoppingservice.com this is what I got:
PING www.nationalshoppingservice.com (184.108.40.206): 56 data bytes ping: sendto: No route to host ping: sendto: No route to host ping: sendto: No route to host ping: sendto: No route to host
So this looks like the DNS is resolving but the route to host cannot be found? What is going on here?
