Alexander,
255.255.255.248 netmask produces 16 IP addresses.
His starts at 142.179.210.232 and goes to 142.179.210.239...
The customary procedure is to throw away 2 of those IP addresses... usually
the first 142.179.210.232 and the last 142.179.210.239 in his case. It is
not a requirement and it should not be a problem if he uses them.

The first one as you pointed out is the NETWORK and it defines the start of
his usable IP range.
The last one is usually the BROADCAST address.
There is nothing though that says these IP addresses are dedicated and can
not be used.
How can you say such a thing? They are reserved for routing purposes
and are NOT valid host addresses. Go back and read your IETF docs.
The whole point of netmasks is to create these special addresses.
You'll confuse the h*ll out of any routers, screw up any BGP, ARP or
RARP tables and generally hose a raft of other things. Do NOT use them
for hosts unless you like debugging flakey networks.
