About this network

TURN-US-ASN belongs to Turn Inc., a digital advertising technology company (demand-side platform, data management, and analytics) based in the San Francisco Bay Area.

What it's used for

• Serving Turn's own advertising platform: bidding, ad delivery, and data processing infrastructure.
• Announces a small block of legacy IPv4 (192.208.220.0/22) plus IPv6.

Notable

• Turn was founded in 2004 and was acquired by Amobee, Singtel's digital advertising arm, in 2017 — so the low AS number is a reissue, not an early-internet allocation. The ARIN org record still carries the Turn name.
• Ad-tech ASNs like this one carry machine-to-machine traffic (real-time bidding and pixel calls) rather than human end users, which is why they appear in traffic logs far out of proportion to their tiny address footprint.
