Summary

ECUTuneFiles

France · AI-generated

business small france

The AS handle SYEOS is held by ECUTuneFiles, operated by Tanguy DELMER.

What it's used for

  • The space carries a single IPv4 prefix 194.15.53.0/24 with netname hyloserv and registrant Private Customer, alongside one IPv6 prefix 2a0c:b641:200::/44.
  • With 256 IPv4 addresses announced against 1 observed neighbour, the inventory suggests a small, self-contained network rather than a transit or large access provider.
  • Reverse DNS entries follow the pattern rev.as200063.net, indicating internal or generic naming without specific technology indicators like DSL or fibre.

Notable

  • The RDAP registrant for the IPv4 block is listed as Private Customer, which differs from the AS holder name ECUTuneFiles or Tanguy DELMER, suggesting the address space may be leased or managed under a private designation.
  • The address inventory is minimal, consisting of one /24 IPv4 block and one /44 IPv6 block, typical of a small business or individual operator.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
