I'm not familar with Apple products,<br />
I have a client does security camera installs<br />
he did a home install where they are running Comcast and a Apple Airport for wireless devices, He was trying to get DDNS setup on a security camera DVR so clients can access DVR remotely when away from home. He ended up reseting the Comcast router and the Apple Airport. Now clients cannot access their email accounts when using the WiFi, they have iPhones and iPADs.<br />
I asked them to try using only the 4G cellular and turn off WiFi on their iPhones and iPADs. email works fine with 4G but when they turn WiFi back on it does not work. The WiFi does give them Internet access not email stops working. Sounds like a DNS issue to me. I'm going to stop by later today to try to resolve. I suspect the Comcast router has to be setup again as well as the Airport. Any advice where to start is appricated.<br />

Thanks

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.

Apple OS

Apple devices including Macs, iPhones, iPods and iPad support standard wired and wireless networking technologies, but they also utilize custom applications and some special techniques for networking with each other and with non-Apple devices. Apple manufacturers the AirPort line of wireless networking products, and has its own networking protocols, AppleTalk and AFP (Apple Filing Protocol).

Apple Networking

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
