IP Ranges API

IP Ranges API

Our IP ranges API returns IP ranges that are owned or operated by a company, identified by domain name. This data will include the total number of ranges and an array with each of them. IP ranges requests can also be used with the IPinfo's batch API.

  • domain:"cloudflare.com",
  • num_ranges:541,
  • ranges:Array[541],

    Advanced usage enabled

    Group up to a thousand
    lookups in one API request

    IP Ranges API can be used with our /batch endpoint. It allows you to group up to 1000 API requests into a single request. This can really speed up processing of bulk IP lookups, and it can also be useful if you want to lookup information across our different APIs.

    We needed to further contextualize Internet scanners, crawlers, and bots. Origin networks, data centers, ASNs, and countries are a huge component of that. We were looking for a faster, more developer-friendly alternative to existing geo-IP providers. A close friend of mine hit the IPinfo API with cURL, and I saw all the information we needed.
