isp residential voip regional
BLAST-PL-AS is operated by Blast.pl, a telecommunications company based in Kraków, Poland.
What it's used for
- The address space carries residential and business internet access, evidenced by reverse DNS entries like
pi128-46.blast.pland netnamesBlast-Net. - The AS announces 768 IPv4 addresses across 2 prefixes and maintains 6 observed neighbours, a ratio indicative of a regional access provider rather than a transit hub.
- Traffic from this AS consists of subscriber eyeballs and VoIP media/signalling, as Blast.pl provides IP transmission, VoIP telephony, and connectivity monitoring services for homes and offices.
Notable
- Registrants for both announced prefixes are
Sebastian Baginski BLAST.PL, consistent with the AS holder. - The address inventory is small and subdivided into two distinct blocks, reflecting a focused regional footprint.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-07, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
