AS14836 — CITY-OF-TORONTO
AS14836 announces 8 IPv4 prefixes covering 70,144 addresses and 0 IPv6 prefixes.
About this network
A sixteen-bit block held since the early allocations, and the routing archive only started seeing it in 2022.
What it's used for
- A municipal government's network. 70,144 addresses across eight IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced. Every block is attributed to Canada.
Notable
- The bulk is 137.15.0.0/16, netname TORNET-01, registered to City of Toronto.
- The remaining netnames run TORNET-02, TORNET-03 and TORNET-04, all to the same registrant.
- TORNET-03 covers four separate blocks in 206.130, from a /21 down to a /24.
- The routing archive first saw this AS in 2022, later than almost anything else in this range.
- Eighteen addresses were queried for reverse DNS and none returned a name.
- The registry lookup for 198.96.187.0/24 failed.
Interesting
- 137.15 is an address block from the era when a sixteen-bit range was something an organisation simply asked for. The city held it for decades while somebody else carried its traffic, and only took its own AS number recently. The allocation and the announcement can be twenty years apart.
- Four netnames, numbered in the order they were acquired, is the tidiest filing habit in this range. Whoever registered the second block copied the first and incremented.
- Two neighbours for a city that runs transit, water and emergency services says the network is a customer of two providers and nothing else. A municipality has no reason to peer.
- Nothing answers a reverse lookup anywhere in it.
