About this network

The registrant field names the same company twice, once with its corporate form and once without.

What it's used for

• A brewer's network. Nine IPv4 prefixes announced from the United States, no IPv6, and two observed BGP neighbours.

Notable

• Every resolved block carries a registrant field holding the company name twice, joined with a semicolon, differing only by the corporate form on the first copy.
• The netnames are BUSCH and BUSCH2, a shortened form of the hyphenated company name with a counter added to the second.
• Eight of the nine prefixes sit inside 170.100, split into pieces from a /22 down to /24 blocks, with one unrelated /19 alongside.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A field containing one organisation listed twice is what happens when a contact record and an organisation record hold the same name and something concatenates both without checking. It is the same defect seen on other holders in this range, and it means an exact-match search for the company name fails against a field that contains it twice over.
• Splitting one range into eight announcements while publishing no reverse names is an inward-facing network: the routing detail exists for the operator's own path selection, and nothing about the addresses is offered to anyone looking in.
• Two upstreams for twelve thousand addresses is thin for an enterprise of this size.
