Start simply with inserting an IPv4 IP address in the online subnet calculator and specify its network mask (Mask bits) in CIDR notation. Then, based on your requirements, specify subnet size by choosing subnet mask (number of subnet bits) and number of subnets you’re looking for.
The subnet calculator lets you enter a subnet range (CIDR) and see IP address information about that range You can type your range directly in CIDR notation, or use the optional Mask pull-down: 74.125.227.0/29
This IP subnet calculator covers both IPv4 and IPv6 protocols, providing information such as IP address, network address, subnet mask, IP range, and more.
Our CIDR calculator can convert a CIDR block into an IP range — and, given an IP range, this CIDR block calculator will find the CIDR notation that captures that range. In this article, we'll cover essential topics such as: What classless interdomain routing is; How to calculate subnet mask from CIDR notation; How to calculate IP range from ...
This online calculator helps you determine whether a network has enough hosts. also provides an easy way of translating between CIDR notation and dotted-decimal format if needed. Enter your subnet to get the subnet mask, wildcard mask, network/broadcast address, and number of assignable hosts.
The Subnet calculator will produce a table with the network and broadcast addresses, netmask, CIDR, wildcard mask, number of addresses in the prefix, first / last host, and address types (Global / Private, Unicast / Multicast, IPv6 link local, and more).
The CIDR Calculator enables CIDR network calculations using IP address, subnet mask, mask bits, maximum required IP addresses and maximum required subnets. Results of the CIDR calculation provide the wildcard mask, for use with ACL (Access Control Lists), , network address in CIDR notation and the CIDR address range for the resulting CIDR network.
