AFAIK, the addresses can be anything from the same network. I traditionally
use .1 as the virtual address, and .2 and .3 as the addresses of the devices
running HSRP. Since you configure each device to run HSRP and tell both
the standby IP address I don't see why the addresses you have available will
not work.
If the HSRP functionality is being added to an existing production network,
you might consider using the current client default gateway as the virtual
address. That way you don't need to visit all the clients to see which
one's are hard coded versus DHCP.

Subject: HSRP and consecutive addressing
Well, this didn't post the first time, so I'll try again.
When implementing HSRP with IP addressing, do the addresses need to be
consecutive? Every sample I've seen lists 10.0.0.1 and 10.0.0.2 (or some
variant) as the router addy's and 10.0.0.3 as the virtual address.
In the real world, however, where HSRP is an afterthought and not planned,
the people who put in static addresses and default gateways don't leave 3 ip
addresses in a block to use. (Obviously they'll have to be the same subnet,
of course) - and they want the old ip addresses on a router to be new the
virtual addy's now -
So could I use 10.0.0.5 and 10.0.0.18 with a virtual addy of 10.0.0.144?
(assuming 255.255.255.0 subnetmask, of course)
No useful info on CCO, so any advice would be appreciated.
