Use the IP range API to retrieve information about the IP addresses that HubSpot uses for various tools such as marketing email or one-to-one emails. This IP address information can be useful to forward to your IT team to configure allowlist rules for your company’s firewall or other network configuration purposes. Check out this Knowledge Base article for related information on troubleshooting other issues with HubSpot notifications and emails.
Please note: the IP ranges returned from the API may change over time. By regularly retrieving the latest IP ranges using this API, you’ll ensure that you’re not using a stale list of HubSpot-related IP addresses in your firewall or network configuration.

​
Retrieve IP range data in JSON format

To retrieve active HubSpot IP addresses, make a GET request to /meta/network-origins/2025-09/ip-ranges. The response will resemble the following: 
{
  "results": [
    {
      "cidr": "3.127.29.218/32",
      "direction": "EGRESS",
      "service": "WEB_SCRAPING",
      "description": "Web crawling and user-generated traffic"
    },
    {
      "cidr": "18.159.155.92/32",
      "direction": "EGRESS",
      "service": "WEB_SCRAPING",
      "description": "Web crawling and user-generated traffic"
    },
    {
      "cidr": "3.125.129.244/32",
      "direction": "EGRESS",
      "service": "WEB_SCRAPING",
      "description": "Web crawling and user-generated traffic"
    },
    {
      "cidr": "54.174.53.218/32",
      "direction": "EGRESS",
      "service": "DNS",
      "description": "External DNS"
    }
  ]
}
Each entry in the results returned in the response will include the following properties:
PropertyTypeDescription
cidrStringThe range of IP addresses used for a specific purpose in HubSpot.
directionStringDenotes the direction of IP traffic. Available values are: "INGRESS", "EGRESS".
serviceStringDenotes the nature of the service for the IP addresses. Values include: "EMAIL", "API", "DNS", "WEB_SCRAPING".
descriptionStringDetails about the purpose of the set of IP addresses.

​
Retrieve IP range data in plaintext format

If you just want to retrieve HubSpot’s IP address data in plaintext format, you can make a GET request to /meta/network-origins/2025-09/ip-ranges/simple and include a header of Accept: text/plain in your request. This will filter the results to just the IP address ranges themselves with none of the other properties in the table above. The response will resemble the following: 
3.127.29.218/32
141.193.185.128/25
18.159.155.92/32
