What is 10.0.0.1?
10.0.0.1 is a private IP address in the 10.0.0.0/8 range defined by RFC 1918. This address space is reserved for use within private networks and cannot be routed on the public internet. It is most commonly used as the default gateway IP for home and corporate routers, particularly in large networks where the 10.x.x.x range provides more addresses than the 192.168.x.x range.
Privacy note
10.0.0.1 appearing in a WebRTC leak test indicates a local network candidate was detected — this is your private LAN IP, not a public leak. Seeing only private IPs (10.x.x.x, 172.16-31.x.x, 192.168.x.x) in WebRTC results is generally not a privacy risk.
