The Subnet Calculator can help you to recognize and use common IP address patterns or categories using the "Pattern" popup menu. This can used to help track down spammers who disguise their IP address in decimal form. The Subnet Calculator will accept a decimal IP address as input and convert to a dotted quad. The host address range shown includes the first and last address of the range which are normally reserved for IPv4 subnet broadcasts and thus are not assigned to individual interfaces. The Subnet Calculator converts prefix lengths into corresponding dotted quad net masks. Two IP addresses separated by a hyphen form an IP address range (example: 192.111.4.0-192.111.15.0). The Subnet Calculator can list the CIDR aggregates for a range of IP addresses. The "Reverse DNS" string is used for address-to-name lookups or "Pointer" (PTR) queries to a name server. The Subnet Calcuator will list the subnets (if any) in the Results box along with the host address range and other information. The Subnet Calculator can determine the CIDR alignment based on the right most 1-bit in the network prefix if an address ends in "/" with no length specified. The prefix length can be entered with the IP Address explicitly (209.68.51.199/24), or if omitted, the subnet calculator will try to determine the prefix length based on the address entered. The length in bits and value of each portion can be adjusted separately. The Subnet box allows you to examine how an IP address is split between a Routing Prefix or network number, a Subnet number (if any), and a Host Interface number (or Group ID for multicast addresses). The Subnet Calculator shows the IP address category or pattern as a description along the bottom of the window below the Results box. The Subnet Calculator makes it easier to understand and specify IP addresses and masks or prefix lengths for routing. The previous IPv4 Only Subnet Calculator is still available by pressing the Option key while selecting the Subnet Calculator tool from the tool menu or launcher palette.

As you adjust the prefix length, subnet length, or any part of the address, the results update accordingly. Enter a prefix length or subnet length in the Subnet area to split the address as desired. The Interface ID was previously known as the "host number", but this is not as consistent since a host can have multiple interfaces. You can split an IP address into 3 parts (routing prefix, subnet, interface ID). The other controls can assist you in specifying IPv6 addresses. Specify an "IP Address or Range" in the Input area.
