About this network

GNB-ORG is the Province of New Brunswick, the Canadian provincial government, registered in ARIN at 435 Brookside Drive, Fredericton. GNB is the standard abbreviation for the Government of New Brunswick.

What it's used for

• Provincial government networking. RIS observes a single announced prefix, 142.139.0.0/16 (65,536 addresses), no IPv6, and exactly one observed neighbour.
• A whole /16 behind one upstream is a public-sector enterprise, not a service provider. A network of that address size that sold transit or hosting would peer with many ASes; this one peers with one. The address space is there to number departments, schools, health facilities and civil-service offices, not to serve external customers.
• The /16 is registered in ARIN to the Province of New Brunswick under GNB-NET-IPV4-1, so the registrant and the announcer are the same body. There is no third-party or leased-space pattern anywhere in the inventory.

Notable

• The card's classification rests on the holder plus the shape of the announcement, both of which are unambiguous. It does not rest on reverse DNS: the sample taken here returned no PTRs on the two addresses checked, which is a sample of two out of 65,536 and is evidence of nothing at all.
• Addresses in 142.139.0.0/16 should be read as Canadian provincial-government space and geolocated to New Brunswick rather than to a generic Canadian carrier.

Interesting

• ARIN dates the ASN to 1999, with the record last updated in 2017. The single-prefix, single-neighbour posture has the look of a long-settled government block that simply has not needed to change.
