Reverse IP

The Reverse IP API provides a list of domain names that share the same Internet host (i.e. the same IP address). You can request an IP address directly, or you can provide a domain name; if you provide a domain name, the API will respond with the list of other domains that share the same IP.

https://api.domaintools.com/v1/64.246.165.240/host-domains/

When a domain name resolves to multiple IP addresses, the ip_addresses response node will have several containers, each with an ip_address, domain_count and domain_names node. Otherwise, those nodes will be included directly as children of the ip_addresses node.

Reverse IP Parameters

Optional Parameters	Value
limit	Limits the size of the domain list than can appear in a response. The limit is applied per-IP address, not for the entire request.

Use the optional limit parameter to control the size of the result list. Domains that resolve to multiple IP addresses may return more than the limit you set if your request is for a domain name instead of an IP address. We recommend requesting explicit IP addresses whenever possible to avoid this uncertainty.

If the domain_count response node is greater than the count of elements in the domain_list node, your query has been limited to only the first set of domains on that IP address, listed alphabetically. The limit may come from your service level or the limit parameter you set in your request.

Sample Response

  response: {
    ip_addresses: [
      {
        domain_count: 1,
        domain_names: ['DOMAINTOOLS.NET'],
        ip_address: '199.30.228.77'
      },
      {
        domain_count: 3,
        domain_names: ['DOMAINTOOLS.COM',
                       'SANTASFAVORITEWHOIS.COM',
