About this network

eir (EIRCOM) — Ireland's incumbent telecom operator, providing fixed broadband, landline, and mobile services. Formerly Eircom / Telecom Éireann.

What it's used for

• Fixed broadband and phone for Irish homes and businesses, plus mobile data (4G/5G) under the eir and GoMo brands.

Notable

• A large "eyeball" network — addresses are consumer home connections and mobile devices, often behind carrier-grade NAT.
• The national incumbent, owner of much of Ireland's copper and fibre access network, competing with Vodafone Ireland and Three Ireland.

Interesting

• The former state monopoly Telecom Éireann, privatized and renamed several times before settling on the eir brand in 2015.
