AS13857 — ONLINEMAC

AS13857 announces 7 IPv4 prefixes covering 16,384 addresses and 1 IPv6 prefixes.

About this network

One netname says the space is sublet, and the reverse names belong to a company that holds only one block.

What it's used for

• A regional internet service provider. 16,384 addresses across seven IPv4 prefixes, the IPv6 block 2604:be40::/32, and six observed BGP neighbours.

Notable

• 187.40.128.0/21 is netname ONW-SUBLET, stating the arrangement in the label itself. It sits in a range administered by a registry in another region.
• Three blocks are netname EUGENE, a city name with nothing else attached.
• 144.86.148.0/22 is registered to a different company, netname XS-MEDIA-3.
• That company's domain carries the reverse names for four blocks the provider itself holds.
• Names are marked dynamic or static, split across two domains, with the address hyphenated in forward order.

Interesting

• A netname declaring space as sublet is unusually honest. Most of this range hides the same arrangement behind initials, and here the registry record states it, which makes the block's chain of custody readable without asking anybody.
• Reverse names in a second company's domain covering blocks registered to the first is the same relationship seen from the DNS side. Whoever runs the resolvers runs both networks, whatever the registry says about who owns which piece.
• A city name as a netname works only while the operator has one city.
