Address facts
- 107.189.18.119
- ROUTERHOSTING (AS14956) · US · reverse DNS 119.18.189.107.static.cloudzy.com (checked 2026-10-19 10:27 UTC)
Network (AS) and country come from the public iptoasn.com routing dataset; a reverse-DNS name is what the address's owner published. Neither shows who controls the hostname: shared hosting, CDNs and cloud providers put unrelated names behind one address.
