About this network

Four absorbed brands still live in the netnames, one of them misspelled on four blocks.

What it's used for

• A national telecommunications operator. Fourteen IPv4 prefixes and one IPv6 /48 announced from Croatia, six thousand six hundred and fifty-six addresses, across sixty-six observed BGP neighbours.

Notable

• The netnames carry four different brands: the current one, a cable brand, a mobile brand, and an internet provider whose name appears on four blocks with the word for access misspelled, a letter short, every time.
• One netname ends with this network's own AS number, so the label names the routing record rather than the customers.
• Another is the words for a customer pool in mixed case joined by an underscore, where the rest are capitals and hyphens.
• Every block lists the same operator contacts; two also name the company under its full legal form.
• Twelve of eighteen queried addresses answered, under two of the old brands: customer equipment marked as changeable on one domain, and a two-letter prefix with the third and fourth address numbers on another.
• Sixty-six upstreams and peers for a network of six thousand addresses.

Interesting

• A misspelling repeated across four blocks is one mistake copied forward, not four mistakes. Whoever registered the second block copied the first, and nobody has read the field closely since.
• Reverse DNS is where acquisitions go to hide. Customer equipment keeps answering under the bought company's domain long after the brand disappears, because renaming it would break nothing and fix nothing.
