Hi Marty,

An IP address is... well, an Internet Protocol address. Pretty much like any other kind of address in intent and application. IP version 4 addresses are 32-bit words usually treated as a sequence of four octets (bytes) and written in the familiar xxx.xxx.xxx.xxx style where xxx is an integer in the range 0 .. 255. Maybe the best known example is 127.0.0.1, the loopback address.

A DNS cache is a set of mappings from host names (e.g. www.besttechie.net) to IP addresses (e.g. 67.43.1.57). Like most caches it's used to speed up operations by keeping data nearby and thereby avoiding the expense of fetching it every time it's needed. In this case the goal is to avoid having to hit remote DNS servers to do host name lookups.

hey thanks.

this discussion was at world start message board.and to be quite honest i thought they were the same.

execpt the dns could be flushed every now and then.

getting back to the ip address.

the loop back reminds me of when at techtv cfh.

we were having trouble with the tivo ad .

which was popping up at will.more so before we logged on.

most of us complained so they published a fix.

we were top go to note pad and change the ip suffix .

from 127.0.0.1 and had to be changed to 127.0.0.0

and it worked.

which was the reason i posted

because i thought it could be done by flushing the dns cache.

but im happy with those replys .

its funny how we can get preconcieved ideas.

and it wasnt until these 2 posts to make me understand.

thanks

marty
