Summary

Datagram s.r.o.

Slovakia · AI-generated

residential isp slovakia

The AS handle ASDATAGRAM is held by Datagram s.r.o.

What it's used for

  • The space carries residential dynamic IP addresses, as evidenced by the reverse DNS record 254.235.131.31.dynamic.sihot.net and the netname DATAGRAM-NET.
  • The network announces 4096 IPv4 addresses within a single prefix (31.131.224.0/20) and maintains only 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for a Slovakian internet service provider.

Notable

  • The RDAP registrant Datagram s.r.o. aligns with the AS holder, confirming consistent ownership of the address space.
  • The address inventory is compact, consisting of a single /20 block with no announced IPv6 prefixes.

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: 436 networks and 1,771 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.
