About this network

OCN (OCN NTT Communications) — NTT's large consumer/business ISP in Japan, one of the country's most widely used fixed-broadband providers.

What it's used for

• Fixed broadband internet access for millions of Japanese homes and businesses.

Notable

• A domestic "eyeball" network — distinct from AS2914, which is NTT's global IP-transit backbone. OCN is the retail ISP; 2914 is the international carrier.

Interesting

• OCN rides on NTT's FLET'S fibre access infrastructure, the backbone of Japan's high fibre-broadband penetration.
