IP Subnet Calculator . The IP Subnet Mask Calculator enables subnet network calculations using network class, IP address, subnet mask, subnet bits, mask bits, maximum required IP subnets and maximum required hosts per subnet. Results of the subnet calculation provide the hexadecimal IP address, the wildcard mask, for use with ACL (Access Control Lists), subnet ID, broadcast address, the subnet. CIDR notation. CIDR notation is a standard syntax for writing IPv6 addresses with a routing prefix. It consists of an IPv6 address, a slash, then a number of bits to measure the routing prefix. 2002::1234:abcd:ffff:c0a8:101/64 is an example of IPv6 CIDR notation Traditionally, the subnet itself must not be used as an address. If we use more bits out of the host space for networking, we can get more and more subnetworks. CIDR Notation. A system called Classless Inter-Domain Routing, or CIDR, was developed as an alternative to traditiona CIDR is the short for Classless Inter-Domain Routing, an IP addressing scheme that replaces the older system based on classes A, B, and C. A single IP address can be used to designate many unique IP addresses with CIDR
