Merged despite the failing lint check; that should have been addresed by #525. If not, I'll follow up with a fix after the main branch build fails. |

Hi!
ParseIPv4Mask("2001:db8::1")currently succeeds as00000001: it takes the last four bytes of any IP address. Consequently, an IPv6 value silently changes anIPMaskflag instead of returning a parse error.Require
To4()before constructing the mask. Keep dotted IPv4, hexadecimal masks and IPv4-mapped addresses working, and leave the flag unchanged after invalid input.Both new regression tests failed before the fix.
go test ./... -count=1,go vet ./...and gofmt pass on Windows/Go 1.27.
