Are you using NAT? Your firewall(s) come from which vendor? Your network
diagram looks like?
I'll assume you have an Internet facing router with a firewall behind it and
maybe routers behind the firewall.

Use two addresses from one ip address block for t

Depending on your config then yes.

If you are connecting a transceiver to either a switch or a hub you will
use a straight-through cable. If you are connecting the hub to the
switch you either must use the uplink port on the hub--if available--or
use a crossover cable. All this is necessary to get the ethernet port

Your problem is one of not enough virtual interfaces. From a switch

is the "vlan 1" interface on vlan 1. If you create a "vlan 13" or other,

A network address can never end in an odd number. Given the IP address
172.16.0.1 and a /21 subnet mask, the network number in this case would be
172.16.0.0. The next network number would be 172.16.8.0 and so forth.

OK first of all 172.16.0.0/21 is actually 172.16.0.0 255.255.248.0
Which means the network address are:
172.16.8.0
172.16.16.0
172.16.24.0
172.16.32.0
172.16.40.0 etc. etc. going up by 8 in the 3rd octet until you hit
172.16.248.0
So the answer is no because 172.16.0.1 falls into the first invali

ends in 172.31.255.255, not 172.31.0.0 as I stated previously.

Given that the very last bit from a binary perspective, it cannot be a

Note that is a reserved for private lan ip, 172.16.0.0-172.31.0.0 is the
reserved block this is part of, that particular /21 would be
172.16.0.0 to 172.16.7.
Interesting. If you have time, can you test again with 'no service config'
set ? I'm curious if it was originally set by service config or something.

Am I missing something. I read the question differently. The way I read it
you were talking about destination address, not source address of the ping.
You can ping the actual IP address of www.cnn.com but cannot ping the URL.
If this is the case, you need to the router to perform DNS lookups. Look
