Summary
jacsa.NET
residential isp hungary ppp
JACSANET is operated by jacsa.NET Kft.
What it's used for
- The address space carries residential broadband access, evidenced by reverse DNS entries such as
ppp-0-85-219-91.jacsa.netandppp-128-180-25-171.jacsa.net. - The AS announces 1792 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio characteristic of an access network rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs connecting via PPP links for internet access in Hungary.
Notable
- All registrants for the announced prefixes are
jacsa.NET Kft., matching the AS holder. - The inventory consists of three distinct IPv4 blocks: 91.219.84.0/22, 171.25.180.0/23, and 193.16.46.0/24.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
