FastNet99 is a network utility that will speed up your web browser every time you want to connect to a web site on the Internet, by avoiding time consuming DNS lookups. It provides all the tools you need to help diagnose network problems and get information about users, hosts and networks on the Internet or on your Intranet. It combines DNS Lookup, Ping, TraceRoute, WhoIs, Finger, Time Synchronizer, KeepAlive and more...

Communications on Internet are based on IP addresses. An IP address is the address of a TCP/IP stack, so if your machine runs a TCP/IP stack, it will have an IP address. When you dial up, your Internet Service Provider (ISP) assignes you an IP address. An example of IP address is 207.68.137.62, that is a sequence of digits that aren't very easy to remind. Therefore when you make your request to your web browser you use the URL address, for example "www.microsoft.com". Your browser may know the IP address associated with the URL simply making a DNS request.

DNS (Domain Name Server) is a service offered by your ISP; it consists of a huge table of URL names and the corresponding IP addresses, so your browser may know what is the correct IP to use for satisfying your request. However, a DNS server cannot hold all exisisting URL-IP addresses but it is linked to other DNS's throughout the world in a hierarchical manner. In other words your web server may ask for informations to another linked DNS until it reaches a "master" DNS server that should have the complete list of IP addresses (there are only 5 "master" DNS servers in the world). This means that your request could imply many requests to other DNS servers while you are expecting for the right reply.

FastNet99 is based on the same idea; it holds a local table of DNS-IP addresses (the Hosts file located on your Windows directory) and tell your browser to check that table before asking the DNS at your ISP. Therefore there is a local search without generating TCP/IP network traffic at all. DNS lookups occur whenever you use URL for finding an Internet resource - so mail, FTP, gopher, IRC can all benefit.

You can manage the table of URL-IP address, by adding entries you are interested in. If you add those DNS lookups that take the longest time to satisfy them, you can take a greater advantage of it.

Besides, you can block unwanted sites by adding entries to the hosts file with the Local IP Address (127.0.0.1). Your machine will not be permitted to seek access to these servers via the Internet, because it will direct your browser to the local computer in search of these sites. Since these are not on your local computer the servers will not be contacted. In this way you can block ads and spyware.
