Description:

This Pull Request introduces a new feature to PeerFinder that allows users to identify facilities that are not shared between Autonomous System Numbers (ASNs). This is particularly useful for network operators who are considering establishing new Points of Presence (POPs) for Private Network Interconnect (PNI) when common facilities are not found.

Key changes:

  • Added a new option to output facilities that are not in common between the specified ASNs
  • Implemented functionality to filter the output of non-common facilities by country code

Benefits:

  • Enables network operators to efficiently identify potential locations for new POPs
  • Provides more granular control over facility output through country code filtering
  • Improves the utility of PeerFinder for PNI planning and optimization

Example Usage:
