Shodan Alternative for Network Intelligence

ipctl.io provides network intelligence that Shodan doesn't: BGP routing, RPKI validation, and prefix analysis - without port scanning.

BGP Routing

Full routing table - which ASN originates a prefix, multi-collector visibility

RPKI & IRR

Route origin validation and IRR cross-referencing for routing security

No Scanning

All data from passive sources. Privacy-respecting network intelligence

Frequently Asked Questions

Is ipctl.io a replacement for Shodan?

Not directly. Shodan and ipctl.io serve different primary purposes. Shodan specializes in internet-wide port scanning, service detection, and device fingerprinting. ipctl.io focuses on network intelligence: BGP routing, RPKI validation, IP reputation, and ASN analysis. If you need open port data, use Shodan. If you need routing and network context, use ipctl.io. Many teams use both.

Does ipctl.io do port scanning?

No. ipctl.io does not perform any port scanning or active probing. All data comes from passive, authoritative sources. This makes ipctl.io a privacy-respecting option for network intelligence.

What does ipctl.io have that Shodan doesn't?

BGP routing data with global visibility, RPKI route origin validation, MOAS (Multiple Origin AS) detection, IRR cross-referencing, and abuse contact lookups from RIR databases. These are critical for network operations and routing security analysis.

Is ipctl.io free?

Yes. All lookups on the website are free with no account required. The REST API offers 1,000 free requests per day. Shodan's free tier is more limited - many features require a paid membership.

Can I use both Shodan and ipctl.io together?

Absolutely. A common setup is using Shodan for open port and service detection, and ipctl.io for BGP routing context, RPKI validation, and IP reputation. Together they give a complete picture of an IP's exposure and network posture.
