Showing 25 of 46 from the live probe.

• Latest Lightning Channels

  Returns the most recently opened Lightning Network channels, sorted by open time descending.

• Ip Reputation

  Check an IP address reputation against 100+ real-time blocklists (DNSBLs). Returns listing status, threat categories, AS info, and blocklist details.

• Lookup Dns

  Lookup DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA) for a given hostname. Also returns domain reputation info (Majestic, Tranco rankings, blocklist status).

• Reverse Lookup Dns Records

  Find hostnames that use a specific DNS record value. Query which hostnames point to an IP address, use a particular nameserver, or reference any DNS value. For example: 'which hostnames point to 1.2.3.4?' or 'which hostnames use chris.ns.cloudflare.com as their nameserver?'

• Reverse Lookup Mx

  Find hostnames that use a specific mail server. For example: which hostnames use aspmx.l.google.com as their mail server?

• Reverse Lookup Ns

  Find hostnames that use a specific nameserver. For example: which hostnames use chris.ns.cloudflare.com as their nameserver?

• Reverse Lookup Ip

  Find hostnames that point to a specific IP address (IPv4 or IPv6). Searches both A and AAAA records. For example: which hostnames point to 1.2.3.4?

• Historic Reverse Lookup Ns

  Find hostnames that *previously* used a specific nameserver but no longer do. Tracks infrastructure migrations and past delegation relationships.

• Historic Reverse Lookup Mx

  Find hostnames that *previously* used a specific mail server but no longer do. Tracks email provider migrations and past MX relationships.

• Historic Reverse Lookup Ip

  Find hostnames that *previously* pointed to a specific IP address but no longer do. Tracks hosting migrations and past IP relationships. Searches both A and AAAA records.

• Lookup Mac

  Look up the manufacturer/vendor of a network device by its MAC address. Uses the official IEEE OUI (Organizationally Unique Identifier) database with ~30K entries.

• Lookup As Whois

  Lookup WHOIS information for an Autonomous System (AS) number from the RADB routing database. Returns routing policy, network information, and administrative contacts.

• Lookup Lightning Node

  Lookup a Lightning Network node by public key. Returns node alias, peer count, channel count, and centrality ranking.

• Lookup Lightning Channel

  Lookup a Lightning channel by channel ID. Supports numeric, block x txn x vout, or block:txn:vout formats.

• Lookup Lightning Channels Per Node

  Lookup all Lightning Network channels for a given node by public key.

• Get Recommended Lightning Peers

  Get recommended Lightning Network peers for a given node. Returns nodes that are NOT currently peered with the specified node but would improve its centrality score if connected.

• Search Lightning Nodes By Alias

  Search for Lightning Network nodes by partial alias match. Returns nodes whose aliases contain the search term (case-insensitive).

• Domain Rdap

  Queries the authoritative RDAP registry for a domain. Returns availability status (HTTP 404 = available), and for registered domains: registrar name, registration/expiration dates, nameservers, DNSSEC status, and domain status flags. Uses IANA bootstrap to find the correct RDAP server per TLD. Covers 590+ TLDs.

• Parse Hostname

  Parse a hostname into its constituent parts using the Mozilla Public Suffix List (9700+ entries). Returns eTLD (effective TLD), registered domain, subdomain, labels, and depth. Handles multi-level eTLDs (co.uk, co.jp, com.au) and platform suffixes (github.io, herokuapp.com).

• Is Subdomain

  Check whether a hostname is a subdomain (has labels beyond the registered domain). Uses the Mozilla Public Suffix List for accurate eTLD detection.

• Registered Domain

  Extract the registered domain (eTLD+1) from a hostname. For example, www.mail.example.co.uk returns example.co.uk.

• Tld Info

  Get information about a top-level domain or effective TLD. Returns whether it is in the Public Suffix List, how many sub-suffixes exist, and classification (ccTLD, gTLD, or infrastructure).

• Reverse Lookup Cname

  Find hostnames that have a CNAME record pointing to the specified target. Useful for CDN and load balancer investigations.

• Historic Reverse Lookup Cname

  Find hostnames that previously had a CNAME record pointing to the specified target but no longer do. Tracks CDN and infrastructure migrations.

• Ip Geolocation

  Get geographic location data for an IP address: country, city, region, latitude, longitude, timezone.
