it's just an old ipv4 silliness about number choices from earlier in my career, and loosely associated with my acquisition of too many rfc1918.$TLD domains.

Perhaps others do this too... I have a tendency to dis-prefer odd numbers (they're surely the devil's work, like left-handed people lol jk) and to prefer numbers in base 4 (who doesn't?). with that in mind, what are 192 and 254 but de-constructible objects of fun within the limits of v4 quad-notation?

```
192 == 64 x 3 == sixty-four PRIMEs, lovely
64 == winrar of numbers, obviously
64 == 16 x 4 == four is best-base, what could be better than four of fours?
64 == 4x4x4 == the best number cubed, lovely.

254 == last addressable IP in a v4 (255 is a downward tangent, we won't go there now)
254 / 64 = 3.96 (evil, clearly)
254 / 4 = 63.5 (almost decent yet part of the curse)
254 / 2 = 127 (everyone knows where home begins)
```

rfc1918.hosts = baremetal hosts
rfc1918.dev = dev systems
rfc1918.io = storage protocol scopes (iscsi, fcoe, roce, ib)
rfc1918.ai = GPU/ML compute VMs
rfc1918.systems = embedded systems
rfc1918.${others}

there are several additional ones that I use for other roles, and while I could use subdomains to sort ... I also already use subdomains to sort. also, whoever owns rfc1918.net needs to sell it to me. :D
