Hello,

I would like to know ideally with some granularity (boardband vs.
narrowband etc) the percentage of user IPs (US & World) that finish in
.0 or .255. I know this is for "internal communications" but I already
know of 2 people who were assigned such IPs by their ISPs. I would
like to know with some precision how prevelent they are. Please give
me sources so I can justify the answer to others as well.

Thanks,

Charles

Hi,
Nobody uses an IP address ending in either .0 or .255 for anything
specifically (for a computer or network device). All IP addresses
ending in .255 are typically broadcast addresses for a particular
subnet and all addresses ending in .0 are addresses which represents
that subnet. For example, 192.168.1.0 is an ip address for a subnet -
the subnet being 192.168.1, and 192.168.1.255 would be the broadcast
address for that subnet - i.e. the address you would use to send a
packet of data to all machines on that subnet.
Regards.
