Ip Addresses

and for the record.. you mean  
255.255.255.0
for the subnet mask.  

pc 1 tries to connect to pc2 and says.. hey...61 is not my network.. so ill send it to my "default gateway".
the default gateway will try and forward it on.  (your internet router most likely)  however, it will probably drop it
as its a private IP address, and not valid on the internet

(it appears to be down??? check back later.. very good resource.)

there is why my link was not working..  hehh

oh ok, thanks for that, what is the subnet mask used for ? :)

oh link is working :)

the subnet mask is used to determine which part of the ip address is for the network and which portion is for the host. for example...

192.168.0.1 with a netmask of 255.255.255.0

in short, the 255 covers the portion of the ip address for the network, so you only have a single octet to use for host addressing.  you are best off going to the website and going through all the lessons because there is a lot that goes into subnetting.

Hey no thats all good thank you, i used http://www.learntosubnet.com which is really good, http://www.howtosubnet.com didnt seem to work :)

Could i ask why my ISP has a subnet of 255.255.255.255 << does it not have a host ID then ? :)

I dont think that is a valid subnet. its for broadcasting or something i thiNK?

and yes.. i think learntosubnet.com used to be called howtosubnet.com.  OR  my memory just is not as good as i thought.
its the same information..

Actually 255.255.255.255 is refered to as a host route.

The three basic types of route entries, HOST ROUTE, NET/SUBNET, and DEFAULT, are described in these paragraphs.

The HOST ROUTE entry describes one particular remote host that may have special routing considerations or forwarding options.
