InetCidr
Classless Inter-Domain Routing (CIDR) that is compatible with :inet and supports both IPv4 and IPv6
Summary↑
| address_count(ip, len) | The number of IP addresses included in the CIDR block |
| bit_count(arg1) | The number of bits in the address family (32 for IPv4 and 128 for IPv6) |
| contains?(arg1, arg2) | Returns true if the CIDR block contains the IP address, false otherwise |
| parse(cidr_string, adjust \\ false) | Parses a string containing either an IPv4 or IPv6 CIDR block using the notation like 192.168.0.0/16 or 2001:abcd::/32. It returns a tuple with the start address, end address and cidr length |
| parse_address!(prefix) | Convenience function that takes an IPv4 or IPv6 address as a string and returns the address. It raises an exception if the string does not contain a valid ip address |
| to_string(arg1) | Prints the CIDR block to a string such that it can be parsed back to a CIDR block by this module |
| v4?(arg1) | Returns true if the value passed in is an IPv4 address, false otherwise |
| v6?(arg1) | Returns true if the value passed in is an IPv6 address, false otherwise |
Functions
The number of IP addresses included in the CIDR block.
The number of bits in the address family (32 for IPv4 and 128 for IPv6)
Returns true if the CIDR block contains the IP address, false otherwise.
Parses a string containing either an IPv4 or IPv6 CIDR block using the notation like 192.168.0.0/16 or 2001:abcd::/32. It returns a tuple with the start address, end address and cidr length.
You can optionally pass true as the second argument to adjust the start ip address if it is not consistent with the cidr length. For example, 192.168.0.0/0 would be adjusted to have a start ip of 0.0.0.0 instead of 192.168.0.0. The default behavior is to be more strict and raise an exception when this occurs.
Convenience function that takes an IPv4 or IPv6 address as a string and returns the address. It raises an exception if the string does not contain a valid ip address.
Prints the CIDR block to a string such that it can be parsed back to a CIDR block by this module.
Returns true if the value passed in is an IPv4 address, false otherwise.
Returns true if the value passed in is an IPv6 address, false otherwise.
