Test the unbracketed IPv6 unspecified address.
LOCALHOST_ADDRESSES includes "::", but this suite only tests "[::]". Add a direct assertion for isLocalhost("::").
Proposed test
expect(isLocalhost("::1")).toBe(true);
+ expect(isLocalhost("::")).toBe(true);
expect(isLocalhost("[::]")).toBe(true);As per coding guidelines, “All features require unit tests using the existing test framework per package.”

Description
Fixed an issue in
extractHostnamewhere IPv6 URLs (e.g.http://[::1]:3000orhttp://[2001:db8::1]:8080) were truncated to a single opening square bracket ("[") because port stripping was splitting on the first colon. Also updatedLOCALHOST_ADDRESSESto include IPv6 loopback addresses (::1,[::1],::,[::]) with O(1)Setlookup.extractHostname.isLocalhostwithSet.has().@plane/utilstesting all URL utilities.Type of Change
