Quote service IPs to prevent YAML misinterpretation

[PseudoResonance]

Why is this pull request needed and what does it do?

IPv6 in YAML needs to be quoted because certain IPs can cause misinterpretations.

One example is an IP ending in a colon, ex: fd:: as YAML thinks it's a new key.

Additionally, I replaced toYaml with toJson on the IP lists. I don't think lists are as problematic, but I figured there might be some edge-case and it's safer to just ensure they're properly quoted. It could be replaced with a range loop and print each IP manually with quotes, but toJson is simpler and still compliant.

Which issues (if any) are related?
