Summary

Computer Systems Consulting s.r.o.

Czechia · AI-generated

business it-services czech

CSC is the AS handle for Computer Systems Consulting s.r.o.

What it's used for

  • The space carries IT infrastructure and office network traffic, evidenced by the netname CZ-CSC-20200109 and reverse DNS entries pointing to npx.cz.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with 2 observed neighbours, indicating a small-scale business network rather than a transit or large access provider.
  • Traffic consists of internal corporate communications, server management, and IT service delivery for clients, consistent with the company's focus on server farms, network administration, and certification services.

Notable

  • The registrant Computer Systems Consulting s.r.o. matches the AS holder, confirming direct ownership of the address space.
  • The address inventory is compact, consisting of a single /24 IPv4 block and a single /29 IPv6 prefix, typical for a specialized IT services firm.

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: 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.
