The tools this server listed when we connected to it, in its own words.
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 blocklistlookup_dns — Lookup DNS records (A, AAAA, MX, NS, TXT, CNAME, SOA) for a given hostname. Also returns domain reputation info (Majestic, Tranco rankings, 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 referencereverse_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 1historic_reverse_lookup_ns — Find hostnames that *previously* used a specific nameserver but no longer do. Tracks infrastructure migrations and past delegation relationshistoric_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. Sealookup_mac — Look up the manufacturer/vendor of a network device by its MAC address. Uses the official IEEE OUI (Organizationally Unique Identifier) datalookup_as_whois — Lookup WHOIS information for an Autonomous System (AS) number from the RADB routing database. Returns routing policy, network information, alookup_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 imprsearch_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: registparse_hostname — Parse a hostname into its constituent parts using the Mozilla Public Suffix List (9700+ entries). Returns eTLD (effective TLD), registered dis_subdomain — Check whether a hostname is a subdomain (has labels beyond the registered domain). Uses the Mozilla Public Suffix List for accurate eTLD detregistered_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, andreverse_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 migrationip_geolocation — Get geographic location data for an IP address: country, city, region, latitude, longitude, timezone.ip_network — Get the containing network (BGP route), AS number, AS name, and route description for an IP address.ip_to_asn — Lightweight lookup: get just the AS number and netblock for an IP address. Fastest way to map IP to ASN.ip_blocklist_check — Check an IP address against IPsum, FireHOL, Tor exit node lists, C2 indicators, Roskomnadzor (Russia), and other threat intelligence feeds. ip_threat_intel — Combined threat intelligence: DNSBL listings, IPsum score, FireHOL lists, bad ASN flag, Tor exit status. Comprehensive threat assessment foras_info — Get the name, organization, country, and description for an Autonomous System number. Lightweight version of as_whois.as_prefixes — Get all IPv4 and IPv6 network prefixes (netblocks) announced by an Autonomous System. Returns BGP-visible routes.domain_reputation — Get comprehensive domain reputation: Majestic rank, Tranco rank, HaGeZi blocklist status, Blackbook malware status, phishing database statusdomain_ranking — Get domain popularity rankings from five independent sources: Majestic Million (backlinks), Tranco top 1M (aggregated traffic), Cloudflare Rdomain_blocklist_check — Check a domain against HaGeZi DNS blocklists, Steven Black unified hosts, Blackbook malware list, phishing databases, Roskomnadzor (Russia),dns_differential — Resolve a domain through filtered public DNS resolvers and their unfiltered controls to detect provider threat-feed blocks.domain_shared_ip — Find other domains hosted on the same IP address(es) as the target domain. Resolves the domain's A records, then performs reverse IP lookupsdomain_shared_ns — Find other domains using the same nameserver(s) as the target domain. Resolves the domain's NS records, then performs reverse NS lookups fordomain_shared_mx — Find other domains using the same mail server(s) as the target domain. Resolves the domain's MX records, then performs reverse MX lookups focheck_email — Verify an email address by connecting to its mail server via SMTP. Checks MX records, tests if the address is accepted (RCPT TO), detects caping — Check if the API is responding. Returns status and server timestamp.Not tested by KitScout yet.
