Summary
Cybernet
isp telecom business
Dynamic and fixed addresses live in separate reverse-DNS zones, and one site gets a zone of its own.
What it's used for
- An internet provider in Belgium. 7,936 addresses across five IPv4 prefixes, one IPv6 prefix, and 16 observed BGP neighbours.
Notable
- Reverse names split between
dyn.cybernet.beand plaincybernet.be, with one address answering213-177-93-126.franco.cybernet.be. - Netnames are
CYBERNET-ISP,CYBERNET-ROOTandBE-CYBERNET-20000322. - One block's registry lookup failed, so nothing here rests on it.
- Twelve of fifteen sampled addresses returned a name.
Interesting
- Separating dynamic addresses into their own subdomain is the single most useful thing a provider can do with reverse DNS. Mail systems and abuse handlers treat the two categories differently, and the label tells them which is which without anyone having to publish a list.
- The extra
francolabel between address and domain marks one site or customer inside an otherwise uniform scheme, so the zone carries structure that the netnames do not. ROOTandISPas netnames describe the operator's own view of its space: the core and the part sold on. Neither follows the dated country-prefixed convention its third block uses, which puts three eras of naming in one record.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
