Network Access Point. A point where networks and service providers hand off traffic to each other. NAPs are typically the points with the worst congestion problems.

A common Internet utility like ping and traceroute. Given an IP address or a DNS address, it will look up and show the corresponding DNS or IP address. There are nslookup utility programs available for every operating system, which you can use with a PPP or networked or shell account. The commonly used FTP program WS_FTP Pro includes a number of utilities including nslookup.But if you have none of those readily available, there are other ways to do the same thing. If you are using Windows 95 or later, there is a traceroute utility built into the operating system. Select Start/Run and type”command”. In the window that opens, type “tracert address” without quotes and substituting the IP or DNS address you want to look up for “address”. It will trace the path to the address, showing all intermediate addresses on the current path, and the IP and DNS addresses for each. More simply, you can type “nslookup address”.Still another utility that will give you the information is WHOIS.
