Version control ports
3 version control ports: what each one does, its protocol, and whether it is secure by default.
SubnetKit lists 3 version control ports, using TCP. 3 of 3 are formally registered with IANA rather than just a widely followed convention.
None of the version control ports here are encrypted by default. Treat traffic on any of them as plain text unless you add TLS, SSH, or a VPN tunnel yourself.
