IPLogs vs Ipregistry
Ipregistry is a credit-based IP geolocation and threat API: every plan returns the full response, including VPN, proxy, Tor and carrier data, after a signup with 20,000 free credits. IPLogs is free with no signup or key and adds a score and every matching signal. Pick Ipregistry for geo, company and carrier data; IPLogs for free detection.
What Ipregistry is
Ipregistry is a commercial IP geolocation and threat-intelligence API covering IPv4 and IPv6. Every plan returns the same full response, including boolean security flags (VPN, proxy, Tor, relay, abuser, attacker, cloud provider) and currency, time zone, company and carrier data. New accounts receive 20,000 free credits, after which usage is paid through a subscription or credit packs that never expire, and an API key is required. Daily offline datasets in CSV and MMDB, a batch endpoint of up to 1,024 IPs and a 99.99% SLA on Enterprise round out the offer.
Pricing, free-tier limits, and feature sets change. Verify current details on Ipregistry before deciding. This page reflects publicly documented behavior as of 2026-11-02.
Side-by-side
| Capability | IPLogs | Ipregistry |
|---|---|---|
| Free allowance for VPN/proxy detection | 1,000 full/day, then fast mode; no key | 20,000 credits at signup, then paid |
| Signup / API key required | No signup, no key | Account + API key |
| Output detail | Score, verdict, every matched signal | Boolean flags: VPN, proxy, Tor, relay, threat, abuser |
| Private Relay, WARP, gateways | is_relay: Private Relay, WARP, browser proxies, secure web gateways | is_relay covers Apple Private Relay only, per docs |
| Protocol probing at lookup | OpenVPN, WireGuard, IKEv2, SOCKS5, HTTP CONNECT, VLESS/REALITY | Method not detailed; cites 220+ OSINT threat feeds |
| Published false-positive rate | 0.4% on a labeled ground-truth corpus | Not stated on its public pages |
| Timezone, currency, company, carrier | None of these fields | In every response, on every plan |
| Bulk / batch size | Up to 100 IPs per request | Up to 1,024 IPs per batch call (credits per lookup) |
| Offline datasets and SLA | No SLA or geolocation database; VPN provider dataset is CC BY 4.0 | Daily CSV/MMDB datasets; 99.99% SLA on Enterprise |
When to choose IPLogs
- You want VPN, proxy and Tor detection with no account, key or credits.
- You need the evidence behind a verdict (each matched signal, its weight and last-seen time), not only flags.
- You want the address probed for VPN and proxy handshakes at lookup time.
- A measured false-positive rate from a labeled corpus matters to you.
When to choose Ipregistry
- You need geolocation, currency, time zone, company and carrier data in the same call as the security flags.
- You prefer pay-as-you-go credit packs that never expire, or a subscription with a stated credit allowance.
- You need batches of up to 1,024 IPs per request.
- You need offline datasets (VPN, proxy, Tor, relay, geolocation) or an enterprise uptime SLA with priority support.

FAQ
Is IPLogs a free alternative to Ipregistry?
For VPN, proxy and Tor detection, yes: IPLogs is free with no signup, key or credits. Ipregistry grants 20,000 free credits at signup and then charges per lookup, but its responses carry far more geo, company, currency, time zone and carrier data than IPLogs returns.
Does Ipregistry return a risk score or only flags?
Its threat-detection docs list boolean fields such as is_vpn, is_proxy, is_tor, is_relay, is_threat, is_abuser and is_attacker. They also say that, at this time, only Apple Private Relay is detected as a relay. IPLogs returns a 0-1 score, a four-level verdict and every signal that matched, and its is_relay covers iCloud Private Relay, Cloudflare WARP, browser proxies and secure web gateways.
What does Ipregistry offer that IPLogs doesn't?
Currency, time zone, company and carrier fields, batches of up to 1,024 IPs, daily offline datasets, never-expiring credit packs, and a 99.99% uptime SLA with priority support on Enterprise. IPLogs has no paid plans, SLA or downloadable geolocation database.
