Essentially, putting a "name" into the browser doesn't get you anywhere. The "name" must be translated into machine recognizable numbers (octets) such as 64.233.167.99 which takes you to Google.com (the Google Search Engine).

That's what DNS servers do; they match the domain name with an IP address using numeric octets and send that info back to the browser. Only then can you connect to the website you wish to visit, whether for surfing, AV updates, Email or posting to and reading Newsgroups. Instead of giving the task to the ISP's DNS servers (or other servers) to do the lookups (resolutions), TreeWalk does this directly from your computer and saves the results for even quicker site access upon the next visit (only during the same session with BIND-LE). TreeWalk uses it's dynamic "cached" library which is held not on the HDD but in RAM, which is much faster. (Not much RAM is required.)

What else it does is more like fixing what the default ISP DNS servers don't or won't do:

• TWDNS allows complete access to all websites and TLDs, not just .com, .edu, .mil, .net, .org and some countries. A few .biz domains may be difficult to resolve, but those are generally server-side issues unrelated to TreeWalk. We can't fix the Internet, but we do improve it's access times.
• TreeWalk provides 99.5% to 100% accuracy instead of the fluctuating accuracy most often experienced with an ISP's DNS servers due to overload or time-outs. It is virtually impossible to overload TreeWalk on a single workstation.
