AS15348 — TUCOWS
AS15348 announces 15 IPv4 prefixes covering 37,376 addresses and 1 IPv6 prefixes.
About this network
Four contact roles per block, listed in a different order on different blocks.
What it's used for
- A domain registrar and internet services company. Twenty-one IPv4 prefixes and one IPv6 /48 announced from Canada, thirty-seven thousand addresses, across two observed BGP neighbours.
Notable
- Most registrant fields name the company plus a network operations centre, an abuse and security team and an operations team, four contacts on one record.
- The order of those roles is not the same on every block: some list abuse second, others third, so the records were written at different times by different hands.
- Most blocks share one netname; the second family uses a variant that drops the final letter of the company name and pads its counter with a zero.
- Sixteen of the routes fall inside one large range, and the remaining five tile a single aligned range that one announcement could carry.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Four named contacts is the most thorough registration in this range. Whoever files a complaint here reaches a team that exists, which is rarer than it should be.
- Publishing nothing in reverse is a surprise for a company whose business includes hosted mail, since receivers score unnamed addresses more harshly. It suggests the mail leaves by other addresses.
- The dropped letter in the second netname is permanent. It has been quoted in every lookup since.
