AS15719 — CZVH

AS15719 announces 2 IPv4 prefixes covering 768 addresses and 0 IPv6 prefixes.

About this network

The only contact on both blocks belongs to a telecoms operator, not to the holder.

What it's used for

• A vehicle inspection company's network. Two IPv4 prefixes announced from Croatia, no IPv6, seven hundred and sixty-eight addresses, across two observed BGP neighbours.

Notable

• Neither block names the holder. The single registrant on both is a contact object belonging to the national telecoms operator.
• The AS handle is a four-letter abbreviation of the company name; the netname is a three-letter one with the country code appended, so the two disagree by a letter.
• Both blocks share that one netname, and the two come from unrelated ranges.
• The routing archive first saw this number more than a decade after the numbers around it, so it was either assigned late or dormant for years.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• A block whose only contact is the upstream provider is managed space. The customer holds the number and the operator holds everything a reader would use to reach anyone about it, which is why the holder's name appears nowhere in the block record.
• Two abbreviations of one name, differing by a single letter, is enough to break every automated match between the routing record and the address record. Both are defensible and neither can be derived from the other.
