- Replace IPv4-only validation with comprehensive address validation - Support IPv4 addresses (e.g., 192.168.1.1) - Support IPv6 addresses including compressed format (e.g., ::1, 2001:db8::1) - Support FQDN/hostnames (e.g., server.example.com, localhost) - Update UI label from 'IP Address' to 'Host/IP Address' - Update placeholder text with examples for all supported formats - Update error messages to reflect new validation capabilities
