  • Added isOctalFormat with regex to detect octal IPv4 representations (e.g., 0177.0.0.1, 01200034567)
  • Updated isPrivate to normalize octal-like IPs
  • Made isLoopback IPv6-mapped detection case-insensitive (::fFFf:127.0.0.1)
  • Improved loopback matching to include zero-padded IPv6 forms (e.g., 000:0:0000::01)
  • Improved loopback matching to handle octal format (017700000001)

Fixes #162
