ip address - Wifi subnet for IP addresses -


i have around 500 ip addresses. 172.45.67.1 - 172.45.67.200. how find wifi subnet these ip addresses? if use java api, great. if not, other technique determine subnet?

your ip range appears part of class b ipv4 subnet based on starting octet value 172.

http://en.wikipedia.org/wiki/ip_address#ipv4_subnetting

as such subnet mask 255.255.0.0.

http://www.subnet-calculator.com/subnet.php?net_class=b

a class b subnet allows maximum of 65,536 addresses.

your building may allocated slice of subnet people administering subnet. however, there no way of knowing how of subnet allocated building without further information (if there 500 addresses, cannot allocated 172.45.67.* there 255 addresses in range).
