CIDR Calculator for IPv4 and IPv6-summary

Online IPv4 / IPv6 CIDR network address calculator, which supports calculating the starting IP, ending IP and the number of hosts in the CIDR block.The IPv4 calculation also displays the subnet mask.

CIDR Calculator for IPv4 and IPv6-instructions
  1. IP Type : Select whether the address type is IPv4 address or IPv6 address.
  2. CIDR : Input CIDR address (Classless Inter-Domain Routing), and calculate the starting IP address, ending IP address, and the number of ip within the CIDR block. The CIDR format of IPv4 is : 192.168.0.0/10. The CIDR format of IPv6 is : 16A0:0010:AB00:001E::2/64. The / is preceded by a valid IPv4 or IPv6 address, followed by a network prefix length.
    IPv4 addresses are in dotted decimal format, such as 114.215.178.166. The address format of IPv6 is colon separated hexadecimal representation, such as 2001:0db8:0000:0023:0008:0800:200c:417a. Continuous 0 compression is supported.
  3. Result :
    1. Network : The network address of the CIDR block.
    2. Start IP : The minimum address of the IP range in the CIDR block.
    3. End IP : The maximum address of the IP range in the CIDR block.
    4. Net Mask :The subnet mask of the IP address corresponding to CIDR. Only IPv4 calculations show this result.
    5. IP Count : The number of IP addresses in the CIDR block.
