Online CIDR calculator

The CIDR Calculator allows you to calculate CIDR networks using your IP address, subnet mask, mask bits, maximum IP addresses and maximum subnets.

The CIDR calculation’s output includes the wildcard mask, which can be used with access control lists (ACLs), a CIDR network address (also known as a CIDR route), and a network address in CIDR notation, and a CIDR address range for resulting CIDR network. 

What Is CIDR?

Classless Inter-Domain Routing, or CIDR, is an IP addressing method that enhances IP address distribution. It takes the place of the previous, classes A, B, and C-based system. Additionally, this plan considerably contributes to the longevity of IPv4 and the moderate growth of routing tables.

Features Of CIDR Calculator

Effective

Variable-length subnet masking underlies CIDR (VLSM). Because of this, it is far more effective approach and can define prefixes of any length.

Convenient

The available IP address space can be successfully managed with the help of CIDR.The quantity of routing table entries can be decreased through the CIDR calculator online.

Compact

As a result of CIDR’s ability to enable IP Address Aggregation, routing tables can be made smaller, which solves many issues.

Frequently asked questions

How does CIDR notation represent an IP address?

An IP address is written as A.B.C.D /n in CIDR notation, where “/n” stands for the IP prefix or network prefix. The amount of significant bits used to identify a network is indicated by the IP prefix. The first 18 bits of a number, like 192.9.205.22, are used to indicate the network, and the final 14 bits are used to identify the hosts.

What are your most popular tools?

Along with the CIDR calculator we also have the effective yet easy-to-use online tools like timestamp converter, free online text editor, json to xml converter online, xpath tester, and alexa free pagerank checker. These tools are free to use and support all browsers and operating systems.

What alternatives exist to overcome the shortcomings of IP addressing?

1.IP version 6 (IPv6) and IP next generation are two options for solving the IPv4 address space restriction (IPng). The most recent IP version is this.

2.Inter-domain routing without classes (CIDR).
