AS15126 — SMAI

AS15126 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

Two blocks in the same range with two blocks skipped between them.

What it's used for

• A marine engine distributor's network. Two IPv4 /24 blocks announced from the United States, no IPv6, and two observed BGP neighbours.

Notable

• The two blocks sit in the same 208.76 range but are not adjacent: there is a gap of two /24 blocks between them that this network does not announce.
• Both carry the same netname, SMA, so the registry cannot tell them apart.
• The AS handle adds one letter to that netname, making a second identifier that sorts next to the first and matches nothing.
• Six addresses were queried for reverse DNS and none returned a name.
• The routing history begins in 2000.

Interesting

• The gap is the detail worth keeping. Two assignments from one range with something else in between means the space was handed out in pieces as it was asked for, and whatever sits in the gap belongs to someone else or was never routed. Anyone summarising this network as a range rather than as two prefixes will include addresses it does not announce.
• A netname and a handle differing by a single character is worse than two unrelated strings, because a human reading them assumes a typo and a machine treats them as unrelated. Neither assumption is useful.
• Five hundred addresses and two upstreams is a distributor's footprint, sized for the company's own systems rather than for anything customers connect to.
