About this network

Telefonica UK (O2) — the O2 network in the United Kingdom, part of the Virgin Media O2 joint venture.

What it's used for

• Mobile internet and home broadband (including fixed-wireless) for UK consumers.

Notable

• An "eyeball" network: addresses here are UK end users, home and mobile, not servers.
• O2 is one of the UK's largest mobile operators; since 2021 it sits alongside Virgin Media's cable network under Virgin Media O2.

Interesting

• The Telefónica/Liberty Global merger that created Virgin Media O2 paired O2's mobile subscriber base with Virgin Media's fixed cable footprint.
