Summary
GRS Sp. z o.o.
business poland corporate
The AS handle GRS-AS is held by GRS Sp. z o.o.
What it's used for
- The address space carries corporate infrastructure, indicated by reverse DNS entries such as
128.grs-e0.g1.pland128.grs-k0.g1.pl. - The network announces 1024 IPv4 addresses across 2 prefixes with 1 observed neighbour, a ratio consistent with a small internal corporate estate rather than a transit or access provider.
- Traffic from this AS consists of internal corporate endpoints for the Warsaw-based real estate property management firm.
Notable
- Registrants for both announced prefixes (
195.62.40.0/23and195.66.144.0/23) are listed as GRS Sp. z o.o., matching the AS holder. - The address inventory is compact, comprising two /23 blocks totaling 1024 addresses, with no IPv6 prefixes announced.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
