It may sound like crazy talk but Amateur Radio was using TCP/IP over the air before the public had general access to the internet. Way back in the early days of internet pre-history BG (before Al Gore). The Department of Defense (DOD) Advanced Research Projects Agency (ARPA) created the Arpanet, which went on to become the internet when the DOD turned over its management.
Radio, as the only mainstream form of wireless communications, was very much at the forefront of what the DOD wanted to see as part of the new ARPANET capabilities. So, Amateur Radio back in the 1970s was specifically allocated an entire class "A" block of IP addresses ("18.104.22.168"), this block is worth millions today so it is worth noting that the internet was a very very quiet place back then. Only serious research was conducted so the allocation was made to "Amateur Radio" use. Presumably, Ham Radio folks without Ph.D.'s were not invited, but in reality, when it took probably many many thousands of dollars invested just to play (i.e. connect) in the game Ham Radio enthusiasts probably couldn't afford it after building their rigs.
Because of the address this network is sometimes called "Network 44." aka AMPRNET - you can still apply for and get an address on network 44 (or more usefully a block of addresses as one IP address is probably not much use) but that's the subject of another article or better yet, Google search.
I only mention network 44 to show how long Ham radio amateur has been a part of the Internet. Unfortunately, the Internet has moved on and Ham Radio has, in some ways, not completely kept up. When you look at some of the Ham Radio applications that connect to the Internet, the feeling that I get, is that kit from the 1990s is being connected to the modern-day internet.
In some cases there seems to be minimal attention to security other than the very basics (a password). Whereas almost everything else being added to the internet these days is forced to operate at a much higher level of security (secure, or https, connections vs public or http connections) because people are more aware of the fact that connections can be listened to, interrupted, modified or changed and information can be stolen. This is not a fault of Ham Radio, because Ham radio by definition allows information to be sent over the airwaves providing that it is not encrypted and the meaning of the information is not hidden. This is of course the complete opposite of the direction that the modern Internet has now taken, where we are trying to encrypt everything that is transmitted.
