Thanks for the input. I don't consider us an isp, though i suppose i can
see how that argument could me made. Hotels are both simple and
complicated. There is a mix of our staff and equipment, guests and their
equipment, and brands with their equipment. But really it's just one
operating entity that ultimayely isn't that much different than any other
enterprise out there. Now multiply that by 60-65 sites spread across the
country and we need to manage our 6000 staff and networks accordingly. We
operate 100% of the hotel, top to bottom, not just the technology.

I wouldn't want ARIN or anyone else thinking we were an ISP if we aren't.
Particulary if that creates problems in the future as rules (and possibly
costs) change.

However, if what you are saying is that registerong as an ISP is actually
the correct way to go about this in ARIN's eyes as well, then that's a
different story.

Thanks for the tip on IoT sizing. That's precisely the kind of thing i am
concerned about being constrained with in the future if we size sites too

Hi Oliver,

I second Ken's notion. You're trying to be an ISP under the end-user rules.
However transient, your users are mostly customers rather than staff. Just
register as an ISP and get the default /32.

IIRC, ARIN sparsely allocates IPv6 so if you go back for more addresses
there is a high probability they'll just increase your netmask.

Finally, /56 or /60 per guest, not /64. IPv6 can do nifty IoT things like
collecting all of a guest's devices behind his personal firewall but it
doesn't work if you've only assigned a /64.
