Unclassified ARIN NSP
Summary
TowardEX
business transit hosting
The AS handle TWDX is held by TowardEX Technologies International, Inc.
What it's used for
- The address space carries corporate and hosting infrastructure, evidenced by reverse DNS entries such as
CARBONITE-I.csw04.bst02.twdx.netandMARKLEY-GRO.csw01.bst05.twdx.net, alongside third-party registrants likeServasticandTaozen Services LLC. - With 11,520 IPv4 addresses and 42 IPv6 prefixes announced against 65 observed neighbours, the ratio suggests a role focused on transit and interconnection rather than large-scale residential access.
Notable
- Registrants are mixed, including TowardEX Technologies International, Inc., Servastic, Taozen Services LLC, and Open Contributors Corporation for Advanced Internet Development, Inc., indicating a portfolio of owned and leased or acquired blocks.
- The inventory consists of 18 IPv4 prefixes, including a large /21 block and numerous /22 and /24 blocks, reflecting a fragmented but substantial address estate.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
