You can create cohorts of users based on their ISP as they were browsing your site. This location data is collected from the user's IP address, using Maxmind's geo-location database. We collect this ISP info on every pageview, so you have this data available as soon as you install Permutive DMP.

To create a cohort of users who have BT as their Internet Service Provider, include users with a pageview where isp_info.isp is BT.
