Exscript.util.ipv6 module

IPv6 address calculation and conversion.


Cleans the ip address up, useful for removing leading zeros, e.g.:

1234:0:01:02:: -> 1234:0:1:2::
1234:0000:0000:0000:0000:0000:0000:000A -> 1234::a
1234:0000:0000:0000:0001:0000:0000:0000 -> 1234:0:0:0:1::
0000:0000:0000:0000:0001:0000:0000:0000 -> ::1:0:0:0
Parameters:ip (string) – An IP address.
Return type:string
Returns:The cleaned up IP.

Returns True if the given string is an IPv6 address, False otherwise.

Parameters:string (string) – Any string.
Return type:bool
Returns:True if the string is an IP address, False otherwise.

Transform the address into a standard, fixed-length form, such as:

1234:0:01:02:: -> 1234:0000:0001:0002:0000:0000:0000:0000 1234::A -> 1234:0000:0000:0000:0000:0000:0000:000a
Parameters:ip (string) – An IP address.
Return type:string
Returns:The normalized IP.
Exscript.util.ipv6.parse_prefix(prefix, default_length=128)[source]

Splits the given IP prefix into a network address and a prefix length. If the prefix does not have a length (i.e., it is a simple IP address), it is presumed to have the given default length.

  • prefix (string) – An IP mask.
  • default_length (long) – The default ip prefix length.
Return type:

string, int


A tuple containing the IP address and prefix length.
