While we don’t use Apple's caching servers we do have transparent caching in place which nets us about 82% of their content being serverd locally. On a big IOS update it will probably be close to 99% for that one title.
Would you be open to elaborating a bit on how that’s set up on your network? :) Regards, Marco Slater On 18 Sep 2017, 14:55 +0100, Luke Guillory <lguillory () reservetele com>, wrote:

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. The caching service does support a lot more than content than "once a year" https://support.apple.com/en-us/HT204675 ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Jean-Francois Mezei" <jfmezei_nanog () vaxination ca To: "Eduardo Schoedler" <listas () esds com br Cc: Nanog () nanog org Sent: Sunday, September 17, 2017 6:43:50 PM Subject: Re: IOS new versions and network loadOn 2017-09-17 19:37, Eduardo Schoedler wrote: Server is an app now, any MacOS can have it running.But do carriers/ISPs really want to deal with a rack unfriendly Mac Mini or iMac at a carrier hotel? 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).
