About this network

Three company names across one block of addresses: one in the registrant field, one in the netnames, and a third in the hostnames.

What it's used for

• A managed email and security provider's network. 72,448 addresses across 16 IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.

Notable

• Seven prefixes carry the netname SILVERSKY-INC-USANET, registered to USA.Net Inc.
• Four carry SILVERSKY-INC-165-212-16, registered to SilverSky, Inc.
• One carries SILVERSKY-INC-USN-BLK-1.
• Three of eighteen sampled addresses returned a name, all of the form net-165-212-175-254.net.perimeterusa.com.
• Almost every prefix falls inside 165.212, from a /18 down to two /22s.

Interesting

• The registry holds one company under another company's netname, and the DNS answers with a third name entirely. Each layer records the owner at the moment that layer was last touched, and none of them gets revisited when the business changes hands.
• SILVERSKY-INC-165-212-16 labels four separate blocks, including one that starts at .128. The digits in a netname are a note the person filing made about the first block they registered, not a field anything checks.
• Three neighbours for 72,448 addresses is a hosted service, not a carrier. The customers arrive over somebody else's network and only the mail has to leave.
• The reverse names spell the address twice, once in the label and once in the address itself, and add nothing else. A hostname like that exists so a log line has something to print.
