Summary
Quest Media & Supplies
business corporate us
QUEST is the AS handle for Quest Media & Supplies, Inc.
What it's used for
- The address space is primarily registered to Quest Media & Supplies, Inc., with netnames such as
QMS-199-47,QMS-207-54,QMS-208-67, andQMS-208-74. - Two prefixes are registered to Fremont Bank (
FBITOPS-25151-94545) and one to First Northern Bank of Dixon (PBI-CUSTNET-9946), indicating leased or transferred space. - The AS announces 6,656 IPv4 addresses across 12 prefixes and has 6 observed neighbours, a ratio consistent with a corporate or business network rather than a transit provider.
Notable
- Registrants are mixed: most prefixes belong to Quest Media & Supplies, Inc., while others belong to Fremont Bank and First Northern Bank of Dixon.
- The address inventory is finely subdivided into /22, /23, and /24 blocks, typical of internal corporate segmentation.
- The reverse DNS sample returned one PTR for
mailgw2.sierracascadenursery.com, suggesting the space may carry mail gateway services for external entities.

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 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,779 prefixes, as published 2026-10-23. 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.
