This calculator returns a variety of information regarding Internet Protocol version 4 (IPv4) and IPv6 subnets including possible network addresses, usable host ranges, subnet mask, and IP class, among others.
Route Summarization Calculator. * Concepts of IP addressing, subnetting, VLSM (Variable Length Subnet Mask), route summarization, IPv6, EUI-64 (Extended Unique Identifier-64) and relevant exam tips, are covered in our CCNA (Cisco Certified Network Associate) course .
This is a Route Summarization calculator . Please enter some route values seperated by spaces (such as 1.2.3.4 1.2.3.5 ), or if it is a range, enter between "-" (such as 172.16.128.0-172.16.159.255 ):
IP Calculator takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. It also helps you design subnets and supernets by giving a second netmask and showing the binary values.
IP Subnet Calculator by Franco For Exams (e.g. CCNA (Cisco Certified Network Associate), CCNP (Cisco Certified Network Professional))
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. 74.125.227.0, then select Optional Mask from dropdown.
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.
