Unclassified RIPE
Summary
Adisam Telecom
isp business
Five scattered /24s, three of them registered to a company called IPv4 Management.
What it's used for
- A Romanian provider network. 1,280 addresses across five IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.
Notable
- The blocks are
217.19.0.0/24,.3.0/24,.5.0/24,.8.0/24and.11.0/24— five non-adjacent/24s in the same neighbourhood. - Three carry the netname
RO-IPV4-20000919, registered toIPv4 Management SRL. - The other two are
ADISAM-TELECOM-SA, and every record shares anIP.RO - NOCcontact. - Fifteen addresses were sampled and none returned a name.
Interesting
- A registrant named
IPv4 Management SRLis a business model in a company name. Once addresses ran out they became an asset class, and companies exist purely to hold, lease and trade blocks. Seeing one as the registrant of space another operator announces is the shape of the market working exactly as intended. - Five
/24s with gaps between them — no.1,.2,.4— means this is a selection from a larger range rather than an allocation. Somebody took the pieces that were free, which is what transferred and leased space looks like from outside. - Announcing five separate
/24s to reach 1,280 addresses costs five routing-table entries where one would do if the space were contiguous. That is the hidden price of an address market: aggregation loses to availability, and everyone else carries the difference.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
