The Services API should warn users about some IP addresses
representations, mainly because some of them are not allowed
by the golang std parsers since go 1.17
Specifically:
- IPv4 addresses with leading zeros, that may cause security risks
- IPv6 addresses in non canonical format, that may cause problems
with controllers hotlooping or cause security issues
