Fixing variable renaming on _find_ipv

On commit [1] the 3rd parameter for _find_ipv() was renamed to fix a
lint issue, but the usage of that parameter wasn't correctly renamed and
a problem arised since there is a class in the same module with that
name (that was being shadowed before). This commit fixes that and add
some unitests for this method so we don't merge this kind of error in
the future.
