Skip toLowerCase() for the documented ipv4/ipv6 families and add a V8 Fast API for one-byte address strings. The FastOneByteString callback takes FastApiCallbackOptions so V8 can use the fast path reliably (required for string-shaped Fast API arguments). Overlong IPv6 zone ids are parsed like uv_ip6_addr (unknown zone is scope_id 0; address parts 40+ chars stay a miss). IPv4 zone suffixes stay a miss, matching uv_ip4_addr.

net.BlockList.check(string)always lowercased the family and went through the slowcheckStringC++ binding. The documented families areipv4/ipv6, so skiptoLowerCase()for those, and add a V8 Fast API for one-byte address strings (no heap allocation; stack-copy +uv_ip*_addr).SocketAddress
check()(already Fast API) is unchanged.This change was implemented with assistance from a closed-source coding agent. I verified the source, official
