invalid memory address or nil pointer dereference on `overlaps` #35

Closed bschaatsbergen closed 2 years ago

bschaatsbergen commented 2 years ago

When executing the following command:

$ cidr overlaps 10.0.14.0/22 10.0.0.0/16a

I seem to get the following error:

$ cidr overlaps 10.0.14.0/22 10.0.0.0/16a                                                                                                                                                  (base)

Closing this issue, seems to be addressed in v0.1.3.

$ cidr overlaps 10.0.14.0/22 10.0.0.0/16a
error: invalid CIDR address: 10.0.0.0/16a
