[ale] Can I tell my Linksys router to always serve the same IP address?

[ale_nospam at fayettedigital.com (Jim Lynch)]

I'd really like to have each machine in my network have a predictible IP 
address, but I also really like the idea that DHCP does more than give 
an IP address (such as furnish DNS info also) so I don't want to just 
set up static IPs for each machine. I'll never have more systems than 
there are available IP addresses, so I really don't need for the router 
to expire the addresses.  So can I tell it to not expire or in some 
other way tell it to keep the same IP for a specific MAC address forever?

Thanks,
Jim.
