For Filecoin and IPFS nodes, Sonar asks each IPNI indexer if your peer is a registered provider. Then it shows the latest state: the CID of the most recent advertisement, or the last error. Check your node: probelab.io/sonar/ @filecoin.io @ipfs.tech

ProbeLab Sonar shows where your node's IP address is located. It also shows if the node runs in a cloud, behind a VPN, or over Tor. probelab.io/sonar/search...

Did your upgrade reach the network? Sonar shows the client version and the protocols that your node advertises. From years of crawler data, it also shows when they changed. You see each upgrade and the day our crawlers first saw it. probelab.io/sonar/

Sonar connects to your node and reads its DHT routing table. The card shows how many peers are in each bucket. Hover over a cell to see their PeerIDs. It also shows how many other peers have your node in their routing tables. probelab.io/sonar/search...

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 🧵👇

We want to add support for more networks, such as Bitcoin, AGNTCY and Monero. If you want to see it in Sonar, tell us: probelab.io/contact/

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.

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

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

While Sonar is being prepared, take the time to play with ProbeLab's ENR Viewer — decode @ethereum.org Node Records in your browser. 🔍 Paste an ENR string, see the node ID, public key, derived PeerID, IP, UDP port, and identity scheme. No CLI needed. Try it: probelab.io/enr-viewer/

How has IPFS performed over the last 7 weeks? @ProbeLab's performance update for Weeks 29–36 (2026) is out! Here are the key takeaways from our network crawlers & probe infrastructure: 🔗 discuss.ipfs.tech/t/probelab-s... 🧵 Glance through all the metrics at: probelab.io

🚀 Speed & Regional Latency: -> Kubo v0.39+ publish gains hold: consistently <1 second. -> Lookup times are fastest in Europe and scale up as requests move east/west toward US and APAC regions. -> Service Worker Gateways show snappy 150–250ms TTFB on cache hits.
