Residential RIPE
Summary
Syrion
isp residential cable dsl
The AS handle SYRION-AS is held by Miconet Sp. z o.o.
What it's used for
- The address space carries residential and business internet access, evidenced by netnames such as
PL-SYRION-SSH,PL-SYRION-Mikemi,PL-SYRION-Henet, andPL-SYRION-SYSTEM, along with reverse DNS entries pointing tosyrion.pl. - The AS announces 26,624 IPv4 addresses across 20 prefixes and 1 IPv6 prefix, with 7 observed neighbours; this ratio of address space to peering partners indicates an access network rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs for cable and DSL services in the Mikolow region of Poland, consistent with the operator's classification as a regional Cable/DSL/ISP.
Notable
- All registrants in the sample are
Miconet Sp. z o.o., which aligns with the AS holder and theSYRION-AShandle. - The address inventory is finely subdivided into multiple /21, /22, /23, and /24 blocks, reflecting site-by-site or technology-specific segmentation within the corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
