About this network

The AS handle ends in a hyphen with the country code missing from behind it.

What it's used for

• A city provider's network. Four IPv4 prefixes announced from Ukraine, no IPv6, four thousand three hundred and fifty-two addresses, across two observed BGP neighbours.

Notable

• The handle is three letters and a trailing hyphen. The holder string carries the same three letters followed by the country code; the handle lost it.
• The four blocks use three netname conventions: two share one form combining the abbreviation, the country code and a network suffix, one drops a letter from the abbreviation, and one uses two letters that appear in neither the company name nor the handle.
• All four list the same company and an abuse role, so the naming varies while the ownership does not.
• The blocks come from four unrelated ranges, the largest a /21.
• The routing archive first saw this number years after the numbers around it, so it was assigned long after its neighbours in the sequence.
• Twelve addresses were queried for reverse DNS and none returned a name.

Interesting

• A truncated handle usually means a field with a length limit that nobody checked after saving. It is cosmetic until something tries to match the handle against the holder name, which no longer agrees.
• Three netname conventions across four blocks, with one identical registrant on all of them, is the registry's most common shape: the ownership fields get maintained and the naming fields never do.
