Hi Kevin,
Thanks for writing. I think I am going to adjust my subnet. We
reserved
the first 50 addresses of our dot 3 subnet for servers and future
growth, so
it's not a huge pool.
We have about 200 clients so the CIDR range with 510 useable IP's
should
suffice. Was there a typo in your post where you suggest that
192.168.3.0/23
wouldn't do? It looks like we should be able to, using the
255.255.254.0
netmask, get the following:
Wildcard Bits 0.0.1.255
First IP in range 192.168.3.0 (network address)
Last IP in range 192.168.4.255 (broadcast address)
First useable IP in range 192.168.3.1
Last useable IP in range 192.168.4.254
Number of useable IPs in range 510
Is this a logic error on my part?
Not a typo.
Actually I posted it with your starting IP range to show that the only way
to get from 192.168.3.0 to 192.168.4.254 was to use the 255.255.248.0 mask,
I did think you would catch it if what I posted was the real CIDR
was192.168.2.0/23, as 192.168.3.0/23 is not a valid CIDR. 192.168.2.0/23 is
the actual CIDR. 192.168.3.0/23 is not valid and the wizard won't accept it,
you have to use 192.168.2.0/23 for the wizard to accept it.
