Summary
First Horizon National Corporation
business finance corporate
The AS handle MARYVILLE-DATA-CENTER is held by First Horizon National Corporation.
What it's used for
- The address space carries corporate infrastructure for a major financial institution, evidenced by netnames
FIRST-HORIZON-NATIONAL-CORPORATIONandIBERIABANK-CORPORATION. - The AS announces 2304 IPv4 addresses across 4 prefixes and maintains 3 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access network.
Notable
- Registrants align with the announcer, with three prefixes registered to First Horizon National Corporation and one to Iberiabank Corporation.
- The presence of the Iberiabank prefix reflects the 2011 merger between First Horizon and IBERIABANK, which resulted in the combined entity retaining the First Horizon name.
- The inventory consists of four contiguous or near-contiguous IPv4 blocks, including a /22 and two /23s, with no IPv6 prefixes in the inventory.

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 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
