During a cidr merge operation, the address 0.0.0.0/0, representing the whole of the IPv4 address space, should swallow anything it is merged with.
|
||
|
|
|
||
|
|
{{{
|
||
|
|
|
||
|
|
>>> cidr_merge(['0.0.0.0/0', '0.0.0.0'])

[IPNetwork('0.0.0.0/0')]
|
||
|
|
|
||
|
|
>>> cidr_merge(['0.0.0.0/0', '255.255.255.255'])
|
||
|

[IPNetwork('0.0.0.0/0')]
|

|
|

Same goes for the IPv6 CIDR ::/0, representing the whole of the IPv6 address space.
|
||
|
|
|
||
|
|
{{{
|
||
|
|
|
||
|
|
>>> cidr_merge(['::/0', 'fe80::1'])
|
||
|
|
[IPNetwork('::/0')]
|
||
|
|
|
||
|
|
>>> cidr_merge(['::/0', '::'])
|
||
|
|
[IPNetwork('::/0')]
|
||
|
|
|
||
|
|
>>> cidr_merge(['::/0', '::192.0.2.0/124', 'ff00::101'])
|
||
|
|
[IPNetwork('::/0')]
|
||
|
|
|
||
|
|
}}}
|
||
|
|
|
||

This also applies to mixed IPv4 and IPv6 address lists.
|
||
|
|
|
||
|
|
{{{
|
||
|
|
|
||
|
|
>>> cidr_merge(['0.0.0.0/0', '0.0.0.0', '::/0', '::'])
|
||
|
|
[IPNetwork('0.0.0.0/0'), IPNetwork('::/0')]
|
||
|
|
|
||
|
|
}}}
