# Win2kPro - Network Connections

I would like to be able to specify an IP range to appear under the "Entire Network" icon.  Currently only the computers with 136.165.85.xxx IPs are listed, I would like to specify a range of say 136.165.80.0 to 136.165.90.254

Only the computers in your subnet will appear.
This is determinsed by the subnet mask.
Class C is
255.255.255.0

I hope this helps !

Subnetting is done with the subnet mask. An IP address consists of a network part and a host part. The subnet mask is used to identify and separate this two parts and to determine, if a given host is on  the same subnet.

A standard subnet mask of 255.255.255.0 tells you that the first three tripletts are the network part   and the forth one is the host part. A subnet mask of 255.255.255.192 adds the two most significant bits  of the 4th triplett to the network part and only the 6 least significant bits identify the hosts. So
you have 4 networks with 64 host addresses each. But since it's not allowed to have only 0s or only
1s in the subnetted part of the network address, you only have two subnets (depending on the OSs and
the routers involved it may work with the other two address ranges). With the example mask above and
an address range of 192.168.0.0 you have these four subnets:
(192.168.0.0)
192.168.0.64
192.168.0.128
(192.168.0.192)
All these calculations have to be done binary.

11000000.10101000.00000000.01000000
11000000.10101000.00000000.10000000

fc, are those other computers in your domain?

fc_hnat : you normally can not access computers in network neighborhood that are outside of your LAN/WAN.
If you provide more info on your system such as what IP range and subnet you are using on your servers, and the infrastructure of your network, we can help more..

I lan is part of an university, and I am just a single computer.  I tried the subnet masks technique, but they did not seem to work.  IE: 255.255.0.0

I just wanted to look at a few computers from other buildings.  I do know some IP ranges.  I am set up as a standalone win2k station, connected as a workgroup.

Depending on the setup, the routers may deliberately be blocking access to other subnets, except for servers or have other restrictions.

I hope this helps !

FC, it doesn't work that way in a Win2000 or NT4 network. If you're in block 136.165.85.xxx to 136.165.89.000, then that's the extent of your browsing, and that's for no other reason than security.

This answers my question, I will just have to go about my problem another way.
