Summary

JSNet S.A.

Argentina · AI-generated

isp residential argentina small

AS27934 is operated by JSNet S.A., an Argentine internet service provider.

What it's used for

  • The address space carries residential or small-business access traffic, as indicated by the reverse DNS record 200-24-245-254.jsnet.com.ar which uses the operator's domain.
  • The network announces a single IPv4 prefix, 200.24.240.0/21, comprising 2048 addresses, with no IPv6 prefixes in inventory.
  • With only 2 observed routing neighbours, the low neighbour count relative to the address block suggests a local access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant for the announced prefix 200.24.240.0/21 is JSNet S.A., which matches the AS holder name exactly.
  • The address inventory consists of a single contiguous /21 block, indicating a simple and focused allocation without fragmented or leased subnets.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
