ProbeLab Sonar is now in public beta! Paste a PeerID, ENR, or Multiaddress to: • Probe your node live & see how the network views it • Compare real-time stats against years of crawler data Try it free 👉 probelab.io/sonar/ What Sonar checks on each network 🧵👇

IPFS: Sonar dials each address of your node and shows which ones other peers can reach. It reads your DHT routing table, counts how many peers have you in theirs, and checks if the IPNI indexers know you. @ipfs.tech @libp2p.bsky.social

Filecoin: the same reachability and DHT checks for your storage provider. Sonar also asks each IPNI indexer if your node is a registered provider, and checks if your Lotus API port is open to the internet. @filecoin.io @fil.org

Ethereum and Gnosis: paste an ENR. Sonar finds the node through discv5. Then it connects over libp2p for consensus-layer nodes, or over devp2p for execution-layer nodes. It also decodes every field of ENR. @ethereum.org @ethereum.foundation

Sonar also probes peers on Celestia, Polkadot and Avail. On every network, Sonar shows the client and protocols that the network sees you run, where your IP address is, and if an admin port is open to the internet. @polkadot.com

Next 🔜 CIDs and Multihashes. Sonar will show who provides the content, from IPNI and the Amino DHT, and check if you can retrieve it. IPNS and DNSLink names follow. We are also planning to surface DNS info. It finds the DNS problems that make libp2p dials fail.

We also want to add cards for each network: · FOC SPs: registry entry, Curio version, deal and retrieval success rates · Ethereum: sync state, fork readiness, PeerDAS custody, validor performance · Celestia: node type and lag · Polkadot and Avail: validator records
