AS13913 announces 6 IPv4 prefixes covering 2,048 addresses and 0 IPv6 prefixes.

About this network

Two alarm monitoring companies share one AS number, and nothing on it answers to a name.

What it's used for

• An alarm monitoring network. 2,048 addresses across six IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

• Four blocks are registered to Affiliated Monitoring, Inc., two of them netname AFFILIATEDMONITORING and two netname AC-359.
• Two are registered to DGA Security Systems, Inc., netnames DGASE-1 and DGA-SECURITY.
• The six blocks are drawn from six unrelated parts of the address space.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• One company filing under two conventions is the ordinary case. AFFILIATEDMONITORING spells the name out and AC-359 is an internal counter, and the two sit side by side because they were filed years apart by people following different habits.
• Nothing in the sample answering a reverse lookup fits the work. An alarm monitoring centre receives connections from equipment installed in customer buildings, and that equipment is configured with addresses rather than names, so a name would serve nobody.
• Six small blocks in six unrelated ranges, behind three upstreams, is a network built for staying reachable rather than for growing. For a business whose product is that the signal arrives, the redundancy is the service.
