# Neustar and PeerLogix

PeerLogix and Neustar announced their identity-resolution relationship in June 2017. Neustar matched household IP activity to cookies and mobile advertising identifiers, connecting viewing audiences to advertising destinations. The relationship supplied early identity resolution and onboarding for the audience business as PeerLogix developed its household graph.

Early identity resolution

Announced June 22, 2017

## Connecting viewing activity to devices

Neustar was PeerLogix’s first identity-resolution partner. PeerLogix supplied household IP-level data, and Neustar returned matched browser cookies and mobile advertising identifiers. These connections made viewing-based audiences usable across advertising channels.

As PeerLogix’s preferred data onboarding provider, Neustar linked identifiers and made PeerLogix audiences available through data management and media platforms. The partnership was announced in June 2017.

## The early household graph

Neustar connected household IP viewing with cookies and mobile device IDs. Neustar’s resolution service supplied the linkage layer for that early version of PeerLogix’s audience graph.

PeerLogix’s 2018 license of Experian’s full identity graph subsequently provided a foundation for building a graph that PeerLogix could expand and maintain through its own signals and additional inputs.
