The request names FernTool, so FernTool comes first: its page shows a public IP lookup covering IPv4/IPv6, ISP, ASN, location and VPN/Tor detection, with a free JSON API and an MCP server 1. Alternatives that do the same job are IP Address API, which returns the public IP with ASN and location in plain text or JSON 3, and IPinfo, which provides IP data via API and SDKs 8.
