# Programmatic and IP-Based Targeting

**Why it's a prerequisite:** Executing block-group-level and household-level spatial strategies relies on modern digital ad-delivery mechanisms.

**What you need to know:** The authors identify **Connected TV and IP-based targeting** as the 'plumbing' that makes high-resolution spatial targeting possible. A basic understanding of how **IP addresses and connected devices map to physical households** is assumed — this is what enables the precision described in [[concept-block-group-resolution]] and the daytime/work signal in [[concept-work-location-proximity]], and it is the infrastructure the authors say already exists in [[action-push-platforms]].
