VPN, Proxy, Mobile and Hosting IPs Explained
Modern IP intelligence classifies addresses into residential, mobile, hosting, proxy and VPN buckets. Here is what each means.
Not all IP addresses behave the same. Lookup tools often flag whether an IP is likely a VPN, proxy, mobile, or hosting provider — useful context for fraud prevention, analytics, and routing.
Residential
IPs assigned by consumer ISPs to homes. These tend to be associated with everyday browsing.
Mobile
IPs owned by cellular carriers. Often shared by many users behind carrier-grade NAT.
Hosting / data center
IPs owned by cloud or hosting providers. Common for servers, scrapers, and VPN endpoints.
Proxy / VPN
Addresses associated with known VPN and proxy services, where the original user IP is hidden behind a tunnel.
よくある質問
Are VPN/proxy flags always accurate?
No — they are heuristics built on observed behavior, ownership records, and ranges. New providers may not be detected for a while.
