AS11358 TENNANT-SOFTWARE

TENNANT-SOFTWARE is a small independent network run by Tennant Software, an entity registered to a Pickering, Ontario address. Despite the low AS number this is a recycled ASN: ARIN records the current registration as February 2024, so nothing about it dates to the early internet.

What it's used for

The inventory is tiny and entirely self-contained. RIS sees 2 v4 prefixes / 512 addresses, 2 IPv6 /48s, and 4 observed neighbours — a handful of adjacencies, which rules out any transit role. Both /24s (23.186.184.0/24 and 168.151.255.0/24) are registered to Tennant Software itself and both wear first-party reverse DNS of the form 23-186-184-5.static.as11358.net. Self-registered space plus first-party rDNS is the clean signature of an operator actually running its own network rather than leasing space out, and the static. naming points at fixed server-style assignments rather than an access pool.

Notable

In PeeringDB the network self-describes as Content with an open policy and lists presence at NL-ix, ONIX and Speed-IX. Treat that as self-reported: every PeeringDB field is, and here the declared shape is bigger than the announced inventory — 512 addresses is not a content platform of any scale. The company's own site is little more than a peering contact page.

Interesting

The likeliest reading is a small self-run hosting and peering network, but the evidence supports the shape rather than the fact, so this one is classified with low confidence. Peering at an Ontario exchange corroborates the registered address.
