To label a vendor's IP addresses or IP ranges, click on Vendors under VENDOR RISK in the sidebar or click here to go straight there.
Once you've clicked on Vendors, your screen should look similar to the screenshot below.
Now it's time to select the vendor. Use the search bar to filter down the results. In the example below, I've searched for UpGuard.
Click on the desired vendor to open up the vendor menu and then click on IP Addresses in the sidebar.
Now that you're on IP Addresses, you'll see a list of your vendor's active IP addresses and IP ranges. To label an individual IP address, click Add label or + (depending on whether the IP address already has a label associated).
Clicking Add label or + will bring up a modal that allows you to update the labels for the IP address.
Click on the labels you want then click Update labels.
If you need to create a new label, search for it in the search bar and click + Create new label.
You can also label multiple IP addresses at once by using the multi-select on the far left of the table and then clicking Edit labels.
