"""Collapse an array of IP objects.
Example: CollapseAddrList(
[IPv4('1.1.0.0/24'), IPv4('1.1.1.0/24')]) -> [IPv4('1.1.0.0/23')]
Note: this works just as well with IPv6 addresses too.
On platforms that support exclude semantics with most specific match,
this method should _always_ be called with complement addresses supplied.
Not doing so can lead to *reversal* of intent. Consider this case:
destination-address:: 10.0.0.0/8, 10.0.0.0/10
destination-exclude:: 10.0.0.0/9
Without optimization, 10.0.0.1 will _match_. With optimization, most specific
prefix will _not_ match, reversing the intent. Supplying complement_addresses
allows this method to consider those implications.
Args:
addresses: list of ipaddress.IPNetwork objects
complement_addresses: list of ipaddress.IPNetwork objects that, if present,
will be considered to avoid harmful optimizations.
Returns:
list of ipaddress.IPNetwork objects
