Summary
Zayo Canada
transit legacy
ZAYO-CAN-6401 is a Canadian autonomous system of Zayo Group, the Denver-headquartered fibre and bandwidth infrastructure carrier. Zayo grew largely by acquisition, and this AS is part of the Canadian assets it absorbed along the way.
What it's used for
- Carrier and enterprise connectivity in Canada: IP transit, wavelengths and dedicated circuits over Zayo's fibre.
- Announces only a handful of scattered
/24s — a small remnant footprint rather than a primary routing identity.
Notable
Zayo is an infrastructure and transit carrier, not a consumer ISP: the address space fronts network gear and business customer circuits, not subscriber pools. Zayo operates several autonomous systems, so an announcement in AS6401 says "a Zayo Canada network element or customer route", not "the Zayo backbone" — the bulk of Zayo's routing lives in its larger, better-known AS numbers.
The tiny announcement count is typical of an AS inherited through acquisition and kept alive for legacy customer routes while new traffic is folded into the acquirer's main network.
