Czechia · AI-generated

business telecom czech

PH is operated by PH, spol. s r. o.

What it's used for

  • The address space carries corporate data connectivity infrastructure, evidenced by the netname PH-CZ and the registrant's business description as a provider of data link sales, distribution, and service.
  • The AS announces 2048 IPv4 addresses within a single prefix (62.182.232.0/21) and maintains 2 observed neighbours, indicating a small-scale business network with limited peering.
  • Traffic from this AS consists of business data connections and backhaul for the operator's customers in the Czech Republic and abroad.

Notable

  • The RDAP registrant PH, spol. s r. o. matches the AS holder, confirming consistent ownership of the announced space.
  • The inventory consists of a single contiguous /21 block, representing a compact and unified address estate.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
