Summary

Dempsey and Clark

Czechia · AI-generated

business dns czechia

The AS handle ASDCC is held by Dempsey and Clark s.r.o.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname DCC-NET and reverse DNS entries pointing to ipv4.dacc.cz.
  • The AS announces 8192 IPv4 addresses within a single prefix (89.22.64.0/19) and maintains only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal business operations and DNS services, as the company is identified as a DNS provider in Prague.

Notable

  • The RDAP registrant Dempsey and Clark s.r.o. matches the registry holder and the AS name ASDCC.
  • The address inventory consists of a single contiguous /19 block, which is finely subdivided for internal use.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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 1,773 prefixes, as published 2026-10-13. 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.
