Summary

SYNOT ICT Services

Czechia · AI-generated

business corporate czechia

SYNOT- is operated by SYNOT ICT Services, a.s.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname CZ-SGS-20070914 and reverse DNS entries like 78-24-237-254.dc-monaco.cz pointing to data center or office systems.
  • The AS announces 2048 IPv4 addresses in a single /21 prefix and one IPv6 prefix, with only 2 observed routing neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal business operations for the Synot group, including IT services and support for their lottery and publishing activities.

Notable

  • The registrant SYNOT ICT Services, a.s. matches the AS holder, confirming direct ownership of the address space.
  • The address inventory is compact, consisting of a single contiguous IPv4 block and a single IPv6 prefix, typical of a corporate estate with minimal external peering.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-01, 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 2026-11-02. 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.
