Summary
Witbe
measurement business hosting infrastructure
The reverse names list the operators this company measures, one customer per probe.
What it's used for
- A service quality measurement company. Eight IPv4 prefixes and fourteen IPv6 prefixes announced from France, four thousand IPv4 addresses, across fifty-three observed BGP neighbours.
Notable
- Three answering addresses sit under a subdomain for cloud and are named after telecommunications operators, including one whose name is an island group's carrier.
- A fourth is a gateway in the operations centre zone, suffixed with a three letter code for a city on the other side of the world.
- Ten of the IPv6 announcements form a staircase, each covering twice the space of the one before, and together they tile one contiguous range exactly.
- Netnames vary block by block: some carry the country code and allocation date, one adds a city abbreviation, one names a different carrier as the holder.
- Eighteen addresses were queried for reverse DNS and four returned a name.
Interesting
- Measuring what customers actually experience means placing probes inside other operators' networks, and the reverse names name those operators. The client list is readable from the DNS.
- Fifty-three neighbours for four thousand addresses fits that work: reaching many networks matters far more than holding many addresses.
- The staircase of IPv6 announcements is space brought into service piece by piece and never reaggregated, which costs every router on the internet ten entries instead of one.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,782 prefixes, as published 2026-10-16. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
