IP Intelligence

Find out who actually runs an IP address.

Built for network engineers, abuse and security teams and researchers who need to know who controls a block right now, not who controlled it last year. Look up any IP address, CIDR, ASN or operator name and see the current routing status, registration and observed PTR evidence, free and without an account.

Search by

  • IP address
  • CIDR block
  • ASN
  • Operator or organization name

What you get back

  • Whether the address space is announced right now and from which ASN
  • The organization on the current RIR registration
  • PTR (reverse DNS) evidence observed across the block
  • How the prefix is carved into smaller, more-specific routes

Free lookup

Look up a network.

See the current routing status, originating ASN, registration and observed PTR evidence for any IP address, CIDR, ASN or operator. Free, no account needed.

viabandwidth presents current public and observed network evidence. An allocation's routing status does not establish whether it is unused, available for sale or lease, transferable, or authorized for a transaction. Confirm ownership, authority and availability directly with the resource holder and the relevant registry.

Network Evidence Report

A current-state summary of routing, registration, PTR coverage and prefix structure for an IP address or CIDR.

  • Current announced or unannounced status
  • Current originating ASN and RIR registration
  • PTR coverage observed at the time of analysis
  • Detected prefix structure and suballocation evidence

Reports are prepared by our team and delivered to your account library within about 24 hours. This is not an instant download.

What it answers

  • Is this address space announced right now, and from which ASN?
  • Which organization is on the current RIR registration?
  • What PTR evidence has been observed across the block?
  • How is the prefix structured into more-specific routes?

Who requests it

Network engineers, abuse and security teams, and researchers who need a documented, point-in-time snapshot of a block they are already investigating, captured in one place they can attach to a ticket or a file.

The report presents clearly labelled current observations only. It does not draw conclusions about whether an allocation is unused, available, transferable or suitable for a transaction.
