About this network

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.net and MARKLEY-GRO.csw01.bst05.twdx.net, alongside third-party registrants like Servastic and Taozen 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.
