*nods* It appears to be very enterprise focused, but then it's mentioned on their PeeringDB page, so that makes one wonder. It doesn't seem like it would be easy for an ISP to manage given that they can't set the required domain search field via static or PPPoE. That would leave DHCP as the only way to assign that field and then that's assuming that whatever router is at the customer location passes that field through to the end user devices. It seems like it would be a lot more effective to ditch the requirement for the domain search field and just let the caching server tell Apple what prefixes it supports and there be an automated verification system using RIR records that the request is legitimate. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Paul Stewart" <paul () paulstewart org> To: "Mike Hammett" <nanog () ics-il net> Cc: Nanog () nanog org Sent: Monday, September 18, 2017 7:53:00 AM Subject: Re: IOS new versions and network load Curious as mentioned if anyone doing this on scale? I kind of doubt it but love to hear otherwise. My assumption is this is more Enterprise focused than ISP Paul Sent from my iPhone

It looks very difficult to manage, given the DNS TXT records and domain search fields. If it was as simple as entering the supported IP ranges, it'd be a lot easier to implement.

If the Server App could run on Linux, or if OS-X could boot on standard servers, perhaps, it it seems to be a very bad fit in carrier/enterprise environments.Implementation will be a little tricky, because you need your customers to look a record in your domain.I've tried reading some about it. The cache server app registers with Apple its existence and the IP address ranges it serves When a client wants to download new IOS version, Apple checked and finds that the client's IP is served by the caching server whose "local" IP is a.b.c.d (akaL the inside NAT IP address). Tells client to get version of software from that IP address. The DNS TXT records are used by the Caching Server to get the list of IP blocks it can serve. (not needed in the target small office environments where everyone is on same subnet and the caching server can tell the apple serves the one subnet it seves).
