Summary

Questora

Poland · AI-generated

business enterprise poland

The AS handle QUESTORA is held by Grid Dynamics Poland Sp z o.o.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname ORG-GDPS1-RIPE and registrant GRID DYNAMICS POLAND SP Z O O associated with the Questora NOC.
  • The inventory consists of 512 IPv4 addresses across 2 prefixes (89.22.4.0/24 and 89.22.7.0/24) with 4 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic from this AS represents office workers and internal services for Grid Dynamics, a publicly traded digital engineering and AI services company.

Notable

  • Registrants align with the announcer, with both prefixes registered to GRID DYNAMICS POLAND SP Z O O under the netname ORG-GDPS1-RIPE.
  • Grid Dynamics is a global digital engineering firm headquartered in San Ramon, California, and publicly traded on the Nasdaq under the ticker GDYN.
  • The address inventory is compact and finely subdivided into two /24 blocks, consistent with site-by-site segmentation for a corporate entity.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
