Is DNS working correctly?
TCP/IP networking and then Internet functions quite happily using IP addresses. Most of the Internet, however, uses the idea of replacing the addresses with names so if it is found that http://www.bbc.co.uk does not work, but 212.58.224.32 does, the assumption can be made that DNS is not set up correctly or the DNS server used is not working as it should. Most devices or software (including Microsoft’s ICS) that provide Internet sharing will provide DNS services to the LAN so usually it is a case of specifying the address of the sharing device as the DNS server, which gain in the case of MS ICS is 192.168.0.1. If for some reason there is no DNS server available on the gateway device, then it will be necessary to configure NTL’s DNS servers on the LAN machines. NTL’s DNS servers are 194.168.4.100 and 194.168.8.100 and it is normal to specify both in the setup.
