Summary

OpticNet Serv

Romania · AI-generated

hosting datacenter business

The AS handle OPTICNET-DUCADU is held by OpticNet Serv S.R.L.

What it's used for

  • The address space carries dedicated server infrastructure, evidenced by reverse DNS entries such as s126-n126.dedicated.opticnet.ro and the netname DUCADU-CLOUD associated with the 193.32.141.0/24 prefix.
  • The AS announces 3,328 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, while maintaining only 2 observed routing neighbours. This high address-to-neighbour ratio indicates a hosting or data center provider rather than a transit carrier.
  • Traffic from this AS consists of web and API endpoints, dedicated server workloads, and cloud services hosted in Ploiești, Romania.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing OPTICNET SERV or OPTICNET-SERV S.R.L. under netnames RO-OPTICNET-20120302 and RO-OPTICNET-20181127.
  • The address inventory is split between two distinct blocks: a larger 37.143.0.0/16 range and a smaller 193.32.0.0/16 range, with the latter specifically tagged for cloud services.

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: 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.
