if Apple keeps a limited # of avenues to bring & keep customers happy; it also would avoid-fake avenues built by fake Engineers/ bankers. Please , please keep a strong trademark? What ever, to communicate with Apple, SAFELY and not wonder what IDMSA is.

Hello, and welcome to the thread.

This is a user-to-user forum. Apple may or may not read postings around here, and only rarely replies. Apple trademarks are way outside our portfolio, too.

IDMSA a cryptic acronym used as the collective name of the group of computer servers — computers larger, faster, and with more resources and capabilities for the billions of network connections happening — used to provide authentication services for controlling and accessing Apple apps and services. That includes the authentication services used to allow (or deny) access here to this Apple Communities.

Much like the network host names you have assigned to your own local computers and other devices, or the network host names that have been automatically generated and assigned, idmsa.apple.com is a network host name.

Here is a partial list of other network host names used by Apple, including the idmsa host:

Use Apple products on enterprise networks - Apple Support

As far as I know, idmsa is not a trademark nor service mark, and not a registered trademark or registered service mark. Nor seemingly intended or appropriate to be one. (But I’m also not a lawyer.)

On this (non-trademark, non-service mark) topic, we can easily get deeper into discussions of distributed authentication, of DNS, of IP routing, and other related topics here, of course. Past its simplistic use, explaining how DNS works or how IP routing or related topics works usually takes a few hours, and often includes an overview of distributed authentication and secure network connections and certificates and usually also involve side-trips into topics in cryptography.
