Hardcoded and unique network addresses for every single device on Earth.
Started with 48 bits (6 bytes), usually given as 01:23:45:67:89:AB but people now encouraged to use 64-bit ones.
How they are assigned: www.quora.com/How-are-MAC-addresses-assigned Basically IEEE gives out the 3 first bytes to device manufacturers that register, this is called the organizationally unique identifier, and then each manufacturer keeps their own devices unique.
As of 2023, working with DNS data is just going through a mish-mash of closed datasets/expensive APIs.
We really need some open data in that area.

TODO was this data also obtained illegally like the Carna botnet
Some interesting usages:
The CIA really likes this registrar, e.g.:
- CIA 2010 covert communication websites
- 2014 www.newsweek.com/former-cia-officials-ready-defend-agency-after-torture-reports-release-290383A group of former CIA officials are gearing up to defend the agency when the Senate releases its long-awaited report investigating "enhanced interrogation" tactics used on prisoners after 9/11. The highlight of their PR push will be a website, "CIASAVEDLIVES.COM," which is set to go live when the report is released on Tuesday, Foreign Policy reported.The domain was registered on November 2 under a private registration name, through DomainsByProxy, a company that guards the identity of registrants.
