IP lookup fields reference
An IP lookup returns metadata about an IP address: who announces it on the internet (ASN), who it is registered to (organization/WHOIS), and approximate location and reputation signals. This page explains each common field, including typical accuracy and pitfalls.
| Field | What it means | Common data source | Accuracy | Notes |
|---|---|---|---|---|
| IP Address | The queried IPv4 or IPv6 address. | Network layer | Exact | IPv6 may be compressed (shortened) in display. |
| IP Version | Whether the address is IPv4 or IPv6. | Network layer | Exact | Some users have both (dual-stack). |
| ISP | Service provider associated with the IP allocation. | RIR WHOIS + commercial datasets | High | Often shows carrier or upstream provider. |
| Organization | Entity that owns/uses the IP range. | RIR WHOIS | High | May differ from the ISP brand name. |
| ASN | Autonomous System Number announcing the IP via BGP. | BGP routing data | Very high | Usually the most reliable ownership/routing field. |
| AS Name | Human-readable name for the ASN. | BGP/RIR | High | May be abbreviated or outdated. |
| Country | Country associated with the IP. | GeoIP databases + RIR hints | High | Country-level is typically the most accurate location field. |
| Region/State | Region/state associated with the IP. | GeoIP databases | Medium | Can lag behind reassignment or routing changes. |
| City | Estimated city associated with the IP. | GeoIP databases | Low–Medium | Often wrong; do not treat as precise. |
| Latitude/Longitude | Approximate coordinates derived from GeoIP. | GeoIP databases | Low | Not GPS—often points to ISP hubs or city centers. |
| Timezone | Timezone inferred from the location fields. | GeoIP databases | Medium | Depends on location accuracy. |
| Postal Code | Estimated postal code (if provided). | GeoIP databases | Low | Commonly missing or inaccurate. |
| Hostname (rDNS) | Reverse DNS name mapped to the IP. | Reverse DNS (PTR) | Medium | Often empty; depends on provider configuration. |
| IP Type | Residential / Mobile / Hosting / Proxy classification. | Heuristics + network metadata | Medium | Different providers may classify differently. |
| Proxy/VPN | Whether traffic appears to come from a proxy/VPN. | Reputation signals | Medium | False positives are possible. |
| Blacklist Status | Whether the IP appears in public blocklists. | DNSBL/RBL sources | High | Results depend on which lists are checked. |
| Abuse Category | Likely abuse type: spam, proxy, malware, etc. | Reputation datasets | Medium | Best used as a hint, not proof. |
| Connection Type | Broadband, mobile, datacenter, etc. (if available). | ISP + heuristics | Medium | May be missing. |
How accurate are IP lookup results?
- Country is usually the most reliable location field.
- City and coordinates are estimates and can be wrong—often by hundreds of kilometers.
- ASN is typically the most reliable ownership/routing indicator.
- ISP/Organization names can be branded differently than the legal registrant.
- Proxy/VPN and blacklist signals are useful hints but can produce false positives.
