Hello to all,

Just need clarification.

A company have been given two static ip addresses for their two computers
i.e. 87.127.173.225 and 87.127.173.226

Would you agree that I can put the following ip addressing on their XP PCs
as follows:-

ip address 87.127.173.225
subnet mask 255.255.255.0
default gateway 87.127.173.1 (I would change the LAN side of the router
to
this)

DNS (whatever it is)


Or does the subnet mask have to be 255.0.0.0?

Many kind regards and thanks for all your help,
Jeff


An IP beginning with 87. is a Class A IP and needs a subnet mask of
255.0.0.0

For information:
Class A 1.0.0.0 to 126.255.255.255
Class B 128.0.0.1 to 191.255.255.255
Class C 192.0.0.0 to 223.255.255.255

Subnet Masks
Class A 255.0.0.0
Class B 255.255.0.0
Class C 255.255.255.0

Hope that helps,
Steve

This network is a small part of a class A subnet, not an entire Class
A subnet, so it doesn't need a Class A subnet mask. A subnet mask of
255.255.255.0 covers all of the specified addresses.

Using a mask of 255.0.0.0 could block access to some Internet sites.
