You can configure an access list to permit the ip's you want and there is an
implicit deny at the end of the access list. For example to permit 10.1.1.1
and deny everybody else: (make sure to apply the access list to an
interface)
access-list 1 permit 10.1.1.1 0.0.0.255

ip helper address can be used to find a dhcp server on a different segment
than what you are. Your computer will broadcast a dhcp request (layer 3
which will not get through a router) for a dhcp server on a different
segment. ip helper address will allow your machine access to the dhcp server
access-list 1 deny 128.252.0.0 0.0.240.255
access-list 1 permit any
the 1st line blocks that range and the 2nd line allows all other traffic
i think? not positive though

Subject: access list..
i dont think the access list here you listed will block the whole range. He
is asking to block the range, not the 2 individual ip addresses.

That should be 0.0.15.255, but that allows 240, and you have it backwards,
you need to permit the first line (access-list 1 deny 128.252.0.0
He wants to block the range 128.252.0.0-128.252.240.0 and permit all else.
access-list 1 deny 128.252.0.0 0.0.240.255
access-list 1 permit any

FAQ, list archives,
if there is an ip address in that range, deny them
if they dont match that range, go to the next line and it permits any
without this last statement, everything would be denied

access-list 1 permit 172.22.0.0 0.0.31.255
It permits all hosts with addresses in the range 172.22.0.1 to
172.22.31.255.

I guess you are going to tell me that Mr. Jeff Doyle is wrong now? Bu-bye
