ASN and IP netblock scraper

Organisation, prefixes and abuse contacts for any network. Find every autonomous system and IP range a company owns. Give it a company name, an ASN, an IP address or a country code, and it returns the owning organisation, its country and postal address, the registry that allocated the number, the registration date, the abuse contact email and phone, and every IPv4 and IPv6 prefix the network announces.

All data comes from the public RIPEstat API and the public RIPE database. No login, no API key, no captcha.

What you can do with it

• Map the full IP footprint of a company before a security assessment or a firewall allowlist.
• Build lists of ISPs, hosting providers and network operators in a country, with abuse contacts attached.
• Turn a log file of IP addresses into named organisations for fraud, bot and traffic analysis.
• Enrich a CRM or KYB record with the registry-level identity behind a network.
• Monitor when a competitor announces new prefixes or registers a new ASN.

Search modes

Search by	What you enter	What you get
Company or organisation name	cloudflare	Every ASN whose registered name matches
ASN	AS13335 or 13335	That one autonomous system
IP address or CIDR prefix	8.8.8.8, 185.60.216.0/22	The ASN announcing that address, plus the matched prefix
Country code	DE, PT, IS	Autonomous systems registered in that country, routed ones first

Input

{
  "searchType": "orgName",
  "queries": ["cloudflare", "hetzner online"],
  "maxItems": 25,
  "includePrefixes": true,
  "maxPrefixesPerAsn": 50,
  "requestDelaySeconds": "0.35"
}

Field	Type	Default	Description
searchType	string	orgName	orgName, asn, ip or country
queries	array	["cloudflare", "hetzner online"]	One value per line
maxItems	integer	25	Hard cap on the number of records
includePrefixes	boolean	true	Fetch announced prefixes. Turn off for faster runs
maxPrefixesPerAsn	integer	50	Cap on stored prefix lists. Counts stay complete
requestDelaySeconds	string	0.35	Polite delay between API calls

Output

One row per autonomous system.

Export the dataset as JSON, CSV, Excel or XML, or read it straight from the Apify API.

Notes

• totalIpv4Addresses counts every announced IPv4 address, even when the stored prefix list is capped.
• Abuse contacts resolve across all five regional registries. Some networks publish a web form instead of a mailbox, in which case the field is empty.
• Country and postal address come from the linked organisation object, so RIPE-region networks return richer detail than some legacy ARIN records.
• The scraper reads only public registry data and paces its requests. It never touches anything behind a login.
