Curious case of Martian traffic in Linux

I use 127/8 for local services, because ports are a very scarce resource. In this respect ip6 is a complete no go.

What would use 1.04e+12 ports? Each IP has about 65k ports IIRC and 127/8 is 16m addresses.

SELinux reserves them for unknown reasons. For all addresses.

I select one 127/16 network for all my addresses - a vendor namespace. Each service can have worker processes, they get 127/24 networks.
