AS13969 — PMM-INC-AS

AS13969 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

Two blocks of the same size, registered to two entirely different kinds of entity.

What it's used for

• A medical billing company's network. 512 addresses across two IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

• The blocks are 170.76.194.0/24 and 198.17.168.0/24.
• The first registers to PROFESSIONAL MEDICAL MANAGEMENT, INC. under the netname PMM-39.
• The second registers to a sole proprietorship under an unrelated netname.
• Routing was first seen in 2000.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• A sole proprietorship holding half the announced space is unusual for a company network. Address space assigned to one legal entity and announced by another is ordinary, but the usual second entity is a carrier or a hosting provider, not a one-person business.
• The -39 on the first netname is a counter, which means the assigning registry had already carved out thirty-eight other blocks under the same scheme. The number says more about the assigner's bookkeeping than about this company.
• Handling medical billing means holding patient records, and this network carries none of the outward-facing surface that would make it look like a healthcare operation from the outside. Two quiet /24 blocks with three upstreams is what back-office work looks like on the public internet.
