How to monitor a vendor's IP addresses and IP ranges

Learn how UpGuard can help you monitor and assess the security posture of your vendor's IP-based assets

A vendor's IP Addresses page shows their IP addresses and IP ranges sourced from DNS records. You must be monitoring the vendor to see this. Learn how to monitor a vendor.

If you're already monitoring the vendor, navigate to Vendor Risk > Vendors in the sidebar.  

Now you’ll need to search for and select the vendor. In this example, I’ll search for UpGuard and select the corresponding row.


In the sub-menu, under the vendor's name, navigate to IP Addresses. You’ll see two tabs IP addresses (1) and IP ranges (2).

IP addresses list the IP addresses monitored by UpGuard for the vendor and can be filtered by services, IP owner, ASN, or IP country. IP ranges monitor the IP ranges associated with the vendor and can be filtered by IP owner, ASN, and IP country.

Selecting an individual IP address brings up a side panel showing the owner, associate IP range, country, autonomous system (AS), autonomous system number (ASN), and any associated domains. If the IP address is not associated with any domains, you’ll see any risks associated with the IP address.


Likewise, clicking into an IP range will show you the owner, country, and number of IPs in the range, as well as any detected IP addresses or domains.
