their network, and need around 30 more ip addresses. I went ahead and
allocated them the following IP address pool (207.66.81.144 ->

address on a Apple Macintosh (PowerMac 6500/75) and it erturned an error

Are you trying to set up that IP address block as one subnet or two?  That
IP block would be two valid /28s (207.206.81.144/28 and
207.206.81.160/28), but it isn't a valid /27.

hint:  For a valid /27 (block of 32 IP addresses), the last octet of the
network address needs to be a multiple of 32.
