Hi All,
Now I am really confused.
Up until this morning I thought I had a good handle on when I need to use
the real Netmask and Broadcast.
For example, If I have 3 servers, and my upline asigns me a block of 128
addresses, for the first ip used (from this block) on each server, I would
need to specify the IP, true netmask and a broadcase. Then, when using more
IPs from that block, I would use a 255.255.255.255 netmask and a broadcast
equal to the IP.
Today, I was in this exact position where I was tring to add an (the first
one one THAT machine, from that block) IP from a block that is almost
completely used up on another server, and the one I was adding it to would
not take it. When I tried adding it with a 255.255.255.255 netmask, and a
broadcast eaqual to the amount of IPs from that block - it worked.
this is on a FreeBSD 4.10 machine.
WHich way is correct for 4.7 and higher?
