That DNS (Domain Name Server) is the DNS # for the internet hosting company. No DNS = NO WEB.

All that is, is that someone manually put that # in probably because they don't know how to setup DHCP or don't have the means to without a router.

as long as they are all connected to the hub and each is running tcp/ip protocol they can get on the internet.. but without a DNS it is useless. Normally using a router you would input the DNS somewhere so it propogates to the pc's, but with a hub it would have to be entered manually.
The DNS is dns.netvision.net.il at least that is what the trace route told me.

The internet workes with numbers. Tcpip addressing. But as you notice most folks hunt down their favorite search engine by their name.

Your ISP uses a dns server. When you type http://www.yahoo.com. The DNS server for your isp converts the name "www.yahoo.com" to the actual tcpip "66.218.71.113".

You actually do need the defination of DNS or you would not need to ask that question.

The internet structure is based on TCP/IP addressing. Every device or site location on the internet is assigned a TCP/IP address.

Question: How does "http://www.techrepublic.com" translate into 216.239.115.148?

Answer DNS. Now go to google and type the following.

define: DNS

and press enter. Because there is just to much to read for us to get into 2000 characters.

Nuff Said

Good Luck Lee
