This address space is reserved for Automatic Private IP allocation. Which is approximately 6.5 billion addresses for everybody on the planet. And while this may seem like a lot, they are going to run out at some point. The need for these networks is because IPv4 has a limited amount of address that can be publicly given out. If you’re on AT&T in the United states, your IP address for your iPhone is using a 10.x.x.x IP Address. Mostly corporations, and larger businesses that need the additional addresses. The 172.16.x.x-172.31.x.x networks, along the 10.x.x.x networks are used for larger networks. Commonly, though, most home routers utilize the .x network. Any ‘private’ network can utilize any of these addresses. There is one more, that I left out, but we’ll get to that in a little bit. IPv4 is the most common form on IP address existing today. IP version 4 (IPv4) and IP version 6 (IPv6). There are two different types of IP Addresses. But we’re going to focus on Internet Protocol or IP. Suffice it to say, that this could easily be a book on just the way that TCP works. The TCP portion within TCP/IP is the actual way that computers talk to each other. The most typical type of address is a Transmission Control Protocol/Internet Protocol Address, or commonly referred to as TCP/IP Address. Some of you may get bored by this section, because you already know about it, but bear with me.Īny device on a network requires an address to be able to talk to any other device. Well I’ll attempt to clear up, and explain what Bonjour actually is and does for you. But you might have no clue exactly what it is or what it actually does for OS X. I know we’ve written about it a bit on Macgasm. What exactly is Bonjour? You’ve probably heard about it.
