That’s mostly because it violates established standards, but you know that already. Lol.
Also, if you’re talking to a network engineer, they probably have PTSD dealing with a client that did this with a 1.0.0.0/8 used internally or some shit and now huge swathes of the internet doesn’t work, but somehow it’s “our fault” that they can’t load random web sites.
I recently had a ticket for a university that had a /12 of public IPs. They gave every computer, printer, etc. a public IP on their whole network. Nothing has NAT. It was insane. They could buy an entire other university building with the money they’d make selling some of that address space down to even a /24.
It’s just a ‘proper’ IPv6 private address, the IPv6 equivalent of ‘10.’.
I say proper as a private address in ipv6 is supposed to be fd, then 40 random bits, then whatever you want. Nothing stops you from having fd::/64 as your private network though. The thinking was people who got tired of merging networks that happened to choose the same 10.x.x.x scheme and/or vpn connecting to multiple sites similarly with the same private address. So they thought it would be swell if every private network on earth would likely be unique, so they said you ‘must’ randomize 5 bytes of it. Then no renumbering/no conflicting vpn connections.
As a Network Engineer: If you did this in my presence, I’d burn you at the goddamn stake. 😂
Like I said … Basically everybody.

Hey, for all you know he might actually be the proper owner of that subnet…
I know if by some crazy coincedence I had that in my subnet I’d be using it for fun.

Fwiw, I now use 10.10.220.0/24. I now know what class A, B and C are. I didn’t then.
Hopefully that offers you some comfort.
Everyone knows you need to be using a network like fd25:c74c:a5e9::/64. So much more fun that way.
I’m sure this is hilarious, but I don’t know enough about IPv6 to get it.

Haha all good homie.
