— What Sonar does
One identifier in. The whole picture out.
History and live state, side by side, from a neutral party. When the two disagree, that difference is the insight.
History
Years of Nebula measurements: agent, protocol, and address timelines with first and last seen.
Live probe
Dial every transport, measure RTT, run identify, and walk the DHT — live from neutral infra.
Geo-map
Every peer, record-holder, provider, and relay placed on the world map via our geoip service.
— How to use it
Paste an identifier. Read the report.
Sonar is free and needs no account. It works with the identifiers that peer-to-peer networks use to name their nodes.
What you can paste
- PeerID: the libp2p identity of a node, for example 12D3KooW…
- ENR: an Ethereum Node Record (enr:-…) of a consensus or execution layer node
- MultiAddress: a network address such as /ip4/…/tcp/4001. Sonar dials it and inspects the peer that answers.
Sonar also recognizes a CID, multihash, IPNS name and DNSLink. For a CID it shows the decoded parts. Live results for these types are not available yet.
What you get back
- The networks in which the node appears.
- Every known address of the node, where it came from and whether it answers.
- The client and agent version over time, and the protocols the node advertises.
- The peers the node keeps in its DHT routing table.
- Its addresses on a world map, and admin ports that are open on its host.
- The decoded parts of the identifier itself.
Who it is for
- Node operators who want to check that their node is reachable and that the network sees the right addresses and version.
- Protocol and client teams who debug a peer that they found in their logs or in the wild.
