block/allow interfaces

[zhuker]

The following will ignore all docker interfaces when gathering candidates

ice.get_host_addresses(block_list=["docker*"])

The following will only allow ethernet interfaces when gathering candidates

ice.get_host_addresses(block_list=["eth*"])

The following will only allow ethernet interfaces when gathering candidates

ice.get_host_addresses(block_list=["eth*"])

It should it be allow_list=["eth*"]) right?

I don't plan on merging this as-is as I can see this leading to a proliferation of options for allowing / blocking not only interfaces but specific addresses. Another option would be to introduce a filter_host_addresses callable which you can use to do whatever you want. This could in fact superseed the use_ipv4 and use_ipv6 parameters.
