AS15935 — HA-VEL-LOCAL-AS ha-vel internet s.r.o.

AS15935 announces 8 IPv4 prefixes covering 50,432 addresses and 3 IPv6 prefixes.

About this network

One hundred and sixty-two neighbours, and the country's name spelled out in the AS handle with a lower-case second word.

What it's used for

• A provider's network. Eight IPv4 prefixes and three IPv6 prefixes announced from Czechia, fifty thousand four hundred and thirty-two addresses, across one hundred and sixty-two observed BGP neighbours.

Notable

• Seven netnames follow one template exactly: a country code, the brand with its internal hyphen kept, and a date. The dates run from a 20001106 block to one taken nearly two decades later.
• The eighth block belongs to a different company entirely, with its own netname, its own registrant and a third company's abuse role.
• The handle inserts the word for a local network before the letters for an autonomous system, then spells out the country with the second word in lower case.
• The company writes its own name in lower case throughout, legal form included.
• Two of the three IPv6 prefixes are /48s from the same range, allocated separately rather than as one block, and the third is a /32.
• One of eighteen queried addresses answered, on a domain matching neither the holder nor any netname.

Interesting

• A hundred and sixty-two neighbours for fifty thousand addresses puts this network among the most connected of its size in this range. That ratio is what a regional provider looks like when its country has a large, open exchange and peering is close to free.
