Summary

Ringier Romania

Romania · AI-generated

media business hosting

Two IPv6 subnets numbered 8888 and 9999, and a mail server with its own address written in hexadecimal.

What it's used for

  • Publishing and online media infrastructure. 1,280 addresses in five IPv4 prefixes, two IPv6 prefixes, and no aggregation between them.

Notable

  • The IPv6 announcements are 2a00:ff0:8888::/48 and 2a00:ff0:9999::/48.
  • Four blocks carry the netname RINGIER-ROMANIA and one is Ringier-DC.
  • Three of them are registered through ABUSE ICI LIR, a sponsoring member rather than the company itself.
  • One sampled address of fifteen answered, as mta127-C1E7CD.mta.ejobs.ro.

Interesting

  • C1E7CD is 193.231.205 in hexadecimal, and 127 is the last octet in decimal. One hostname, two number bases, describing the same address twice. It is the second scheme of this kind in this stretch of the number range, which suggests the tooling that produces it is more common than it looks.
  • mta is a mail transfer agent, named twice in one hostname. Bulk mail senders label their outbound machines carefully because receiving systems judge reputation per address, so the naming is aimed at other mail servers rather than at people.
  • Repeated digits in a subnet number are a human choice. IPv6 gives an operator 65,536 subnets in a /32 and no reason to prefer any of them, so somebody picked 8888 and 9999 because they are easy to remember and type — the same instinct that produces memorable phone numbers.

Reputation

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 1,784 prefixes, as published 2026-10-19. 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.
