IP CALCULATOR

This IP calculator takes the IP address and netmask and calculates broadcast, network, Cisco wildcard, etc. You can use it for IPv4 and IPv6 networks... When you are building a large network, sometimes it can get too big to handle. Not only can this be difficult to manage but it can also slow down traffic and pose major security risks. Breaking down this large network into smaller networks - an act called "subnetting" - can increase network efficiency, make it safer, and make it easier to maintain.
