How to verify a provider result
Enter the public IP you want to check and compare the returned organization and ASN with this NTT / OCN profile. Retail brands, registered address holders, and routing operators may differ, and one brand can use several networks. One ASN example is not a complete inventory of the brand’s address space.
Your current IP is the HTTP exit used to reach this site. Lookups use external IP intelligence services.
