The previous regex-based scan fragmented IPv6 addresses on colons, causing all IPv6 no_proxy entries to be silently ignored. Replace scan with split-then-branch parsing that handles four formats: - Bare IPv6: 2001:db8::1, 2001:db8::/32 - Bracketed: [2001:db8::1] - Bracketed with port: [2001:db8::1]:8080 - IPv4/hostname: example.com, 10.0.0.1:8080, example.com: (trailing colon) Also strips zone IDs (e.g. ::1%eth0) before IPAddr matching, and reads $2 before calling sub() to avoid global match variable clobbering. Fixes ruby#218

There was a problem hiding this comment.
The next in the rescue IPAddr::InvalidAddressError clause was removed as it is redundant. Falling off the end of the block body advances to the next iteration identically to calling next explicitly. No behavioral change.
