Unclassified ARIN
Summary
World Communications
isp telecom hosting
The one address that answers does so under another country's domain, with its octets fully reversed.
What it's used for
- A communications provider's network. 2,048 addresses in the single IPv4 prefix
209.213.184.0/21, two observed BGP neighbours, and no IPv6 announced.
Notable
209.213.189.254answers as254.189.213.209.server-hosting.co.cr, the address backwards in dotted form.- The domain sits under a country code that is not the one the block is announced from.
- The block is netname
WCS-BLCK-1, an initialism and the word block with its vowel removed. - The registrant and the AS handle are the same two words.
- Three addresses were queried for reverse DNS and one returned a name.
Interesting
- A reverse name that is the address written backwards, with the dots kept, is the raw form of the lookup itself with a domain glued on the end. Whoever built the zone automated it from the query rather than from the address.
- The hosting domain belonging to another country says who operates the machines, which is not the same as who announces them or where the addresses are registered. Three answers to what should be one question.
- Dropping a vowel to shorten block to four characters, in a field with room to spare, is a habit from systems that once counted every character.

Internet exchanges
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 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
