> It never really took off though, and even back in its early days it saw barely any use. Over the years it just deteriorated further, and today it's basically completely dead.
It's actually not completely dead... It's just (almost) completely non-public.
You can subscribe to services to get number porting information where the interface is basically e164.arpa queries to a private nameserver over a VPN. I don't know the details, the cost was high enough that it didn't make sense for my employer to pursue it.
It's also not uncommon for telecom providers to use it for their own internal routing because enough telecom software did in fact develop support for it despite lack of public implementations.
As someone who's been in the VoIP industry for over 20 years it makes me sad to think of what could have been if both ENUM and IPv6 were more widely adopted. For many years you could reach me via email, SIP, or Jabber with the same identifier and if there were effective support for ENUM in the USA my work phone number would have been able to connect you to any of them, directly and with G.722 HD voice long before it eventually came to modern cellular networks.
I know opinions about Mitnick are quite divided. But I enjoyed reading "Ghost in the Wires" (https://www.goodreads.com/book/show/10256723-ghost-in-the-wi...). It's giving this 90s-era hacker vibe that's kinda fun (even if the truth might be stretched a bit).
The article mentions Ascension Island, a small island in the south atlantic. There's a really great spy novel that takes places there, Ascension by Oliver Harris.
This is a great story. Almost wish the author had dug a little further in and discovered something like Clifford Stoll in The Cuckoo's Egg, but a nice writeup nontheless.
Makes me wonder how many partly implemented but ignored protocols like this exist.
Having looked into the matter, 4000 people live there. It's entirely possible there are subscribers outside the base, so numbers for that area aren't neccesarily terminated at the base. That said, it's likely. Military IT is rumoured to be outdated and awful.

> So I had accidentally logged hundreds of thousands of phone numbers and timestamps for calls going to military bases.
That's quite a jump to conclusion right there.
