Ip addresses in new router

I just installed a new router for my home wireless LAN running XP and am now
working on the security setup.

I have WPA successfully working and noticed that all my 3 networked PCs now
have sequential IP addresses set as ......100, ......101, .....102, etc.
while the router's ip is at .........1.

Is there any advantage in:
a) changing these ip addresses to somewhere more in the middle of the range
(....158/9, etc)?

b) how do I do that? I suspect by leaving the TCPIP setting to "Obtain IP
address automatically" while assigning an IP address in the "Alternate
Configuration" screen, but I am not sure and would welcome advice.

c) is there then a security advantage to limiting the available IP range in
the router to a smaller range of IPs instead of it's present wide .......1
to 255?

Thanks

Hi
The actual number of the IP does not matter, there is No advantage in one
number or the other.
However if it bother you, log to the Router's menus, look for the DHCP
server section, and change the range of the IPs. I.e. If you would insert
there 192.168.1.100 to 192.168.1.120 it would assign numbers from 100 to
120.
