AS14939 — THRES

Network type: residential

AS14939 announces 2 IPv4 prefixes covering 512 addresses and 2 IPv6 prefixes.

About this network

Two IPv6 blocks the size most providers get one of, against 512 IPv4 addresses.

What it's used for

• A communications provider's network. 512 IPv4 addresses across two prefixes, two IPv6 prefixes, and three observed BGP neighbours.

Notable

• The IPv6 announcements are 2604:5000:1000::/36 and 2604:5000:2000::/36, two pieces of one larger range announced separately.
• 67.206.179.0/24 carries the netname THRES and 199.191.62.0/24 carries THRES-BLK-4.
• That second netname counts to four, though only two blocks appear here.
• Three addresses answer as 199-191-62-64.threshinc.com, under a domain that shortens the company name differently again.

Interesting

• The imbalance between the protocols is the striking part. This provider announces fewer IPv4 addresses than a small office building might use, and enough IPv6 to number every device in a city twice over. That is not ambition; it is what the allocation policies of the two protocols produce when applied to the same company.
• Splitting one range into two announcements rather than one is a choice about traffic engineering, and it doubles this network's contribution to the global table for no change in what is reachable.
• A netname counting to four with two blocks visible means two more exist somewhere, unrouted or announced elsewhere. Counters in netnames are one of the few places the registry accidentally records what is missing.
• Three shortenings of one company name, across the handle, the netname and the domain, is the usual state of affairs here.
