IPCombo vs WhatIsMyIP vs IPinfo: which IP checker to use
Three popular IP checkers, three different philosophies. WhatIsMyIP and IPinfo show you a single IP. IPCombo shows you one IP per destination — so you can see exactly which proxy rule fired for each site. Here's the breakdown.
Last verified: 2026-09-23
| Dimension | IPCombo Per-target IP, ASN, and routing inference | WhatIsMyIP Simple single-IP echo, longest-running brand | IPinfo Single-IP + rich IP intelligence (paid API) |
|---|---|---|---|
| Single IP echo | Yes — per destination | Yes — one IP per request | Yes — one IP per request |
| Per-target real IP | Yes — 34+ destinations in one run | No — collapses to single number | No — collapses to single number |
| ASN / network class | Yes — shown inline per target | Partial — ISP only | Yes — rich ASN data (paid) |
| Routing inference (direct / proxy) | Yes — per-target direct/proxy inference | No | No |
| WebRTC leak visibility | Yes — full candidate breakdown (host / srflx / relay) | No | No |
| Multi-exit IP detection | Yes — surfaces 2-3 exits when each exits 1 IP | No — single IP per check | No — single IP per check |
| Cloudflare edge (colo code) | Yes — per-target via cdn-cgi/trace | No | No |
| GeoIP detail | Country, region, city, ISP, ASN per IP | Country, region, city, ISP | Country, region, city, ISP, ASN (paid) |
| Price (consumer) | Free | Free | Free for single lookup; API starts $49/mo |
| Privacy (no logs) | All probes run client-side; no server logs | Logs requests, serves ads | Logs requests (paid tiers anonymized) |
| Best for | Proxy users debugging routing, multi-exit IP verification, ASN-class debugging | Quick casual IP lookup, no proxy setup | Programmatic IP intelligence (batch API) |
Bottom line
If you just need to know 'what is my IP' once a month, WhatIsMyIP is fine. If you're a developer building IP intelligence into your stack, IPinfo's paid API is unbeatable on data quality. If you have a proxy, VPN, or split-routing setup and want to know which rule fired for each destination — IPCombo is the only one of the three that gives you that answer. It's the only one that does multi-exit detection, per-target routing inference, and WebRTC candidate breakdown side-by-side.
