Judging by your excitement, the next big thing to git in on would be naming the next hit technology "glto" so that when GLTO reaches 25 years old we can have national #GLTODay and I am sure we all know what will happen on this day

You're mistaking rabies for excitement. But yes, that would be most cool.

#CIDRDay gave you rabies? I must have misinterpreted

Yet some things still predict the Net mask based on former class size.

Yes, broken and/or obsolete things.

I have a number of obsolete computers that predate CIDR. To make it easier to use them, in 1994 I added a feature to the Netblazer router called bozoarp which would automatically proxy-arp for any received ARP request outside the configured network on an interface.

Slightly later I wrote "anyipd", a daemon for FreeBSD to do the same thing. It was written for a client, and the motivation was slightly different.

Before DHCP became ubiquitous, a hotel chain wanted to provide wired Ethernet without requiring guest to change their IP configuration. The anyipd daemon was only a portion of the solution; there was another part that did the IP address rewriting.

I’m not surprised. I saw something like that feature in a router YEARS ago. (Early 2000s.) I think it was Star<something>. The last time I looked for it they were gone or multiple acquisitions / sales related name changes later and couldn’t be found.

I was surprised that no one in management or marketing at Telebit objected to my naming the feature bozo-arp. I originally put it in as a hidden command, just for my own use, but another engineer pointed out that it would be useful to some customers as well.

One machine I used it with, and still on rare occasions do, is the AT&T Unix PC (7300 or 3B1). System V Release 2 with a crappy TCP/IP stack. Crappy mostly because of limitations in SVR2. Sockets kludged in, no real support for select() or even poll(). Predates CIDR.
