About this network

PUBNIX2-ASN belongs to PubNIX Inc., a long-established Canadian internet company operating out of the Montreal area (registered in Beaconsfield, Quebec).

What it's used for

• Colocation, web/email hosting, and virtual machines out of a downtown Montreal data centre.
• Subscriber access links (DSL and cable) for customers in Quebec and Ontario.
• Network consulting work — BGP, IPv6, load balancing, and data-centre infrastructure.

Notable

• A mixed hosting and access network: much of the space sits in front of servers and colocated customer equipment, with a smaller access-subscriber component alongside it.
• Small and independent. The address footprint is a few thousand IPv4 addresses, typical of a regional hosting provider rather than a large cloud.

Interesting

• PubNIX has been operating since the mid-1990s, from the era when a single small company could hold its own AS number and peer directly — hence a number this low for a business of this size.
