Unclassified ARIN
Summary
TransUnion Interactive
finance enterprise legacy
The network of TransUnion Interactive, the arm of the credit bureau TransUnion that deals directly with consumers.
What it's used for
- Consumer-facing credit services. 2,048 addresses in two
/22s, three observed BGP neighbours, no IPv6 announced.
Notable
- Reverse DNS is generated from an address plan rather than written by hand. Sampled names include
net.sd.demo.truelink.comandbcast.xo-pvt.tuint.net— the network and broadcast addresses of subnets, labelled as such — andunallocated.truelink.comon space not yet handed out. - The
xo-pvtlabel marks a private circuit from XO Communications, one of the US carriers that sold point-to-point links alongside internet transit. - Both blocks are registered as
TRUELINK-BLK1andTRUELINK-BLK2, withTrueLink NOCandTrueLink ARIN Techas contacts.
Interesting
- Four names for one company are visible at once. The registrant reads Transunion Interactive, the AS handle is
TRUELINK, the netnames sayTRUELINK, and the reverse DNS answers on bothtruelink.comandtuint.net. TrueLink was the independent company TransUnion bought to run its consumer side; the acquisition changed the letterhead and left everything a network engineer touches exactly as it was. - A bureau that holds credit files on most adults in the country needs somewhere for those adults to log in, and that is a different problem from the bulk data exchange it does with lenders. Its own company, AS and address space is a reasonable answer.
- Naming the broadcast address of every subnet in DNS is a habit from an era when engineers read
tracerouteoutput unassisted. It costs nothing and it still saves a minute.

Peering at a glance
Internet exchanges
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 2026-11-10, 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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
