I think most people think mac addresses are a bit strange. They are, but I think the majority of them are just that.
Most of the time we’re talking about the default “address” field in your own computer’s system settings. Macs come with two default addresses. This “address” is what your system uses for sending and receiving messages and files. Macs also come with a “domain”, which is the name your computer has assigned to the address.
This is an easy one to answer. If you are using windows, you have to use the domain field. If you are using linux, you don’t.
One thing that you can do is set up a mac address and use it for both your main email address and the domain name as well. This way you can use the two to send mail and files without having to change the default address or change what your computer is set to use for your domain. I usually go for the mac address.
If you set up a mac address, you have to change the domain to the mac address. You can’t use the mac address on the domain field. I dont use mac addresses for domain names. I just stick with the domain field.
Mac addresses are usually used for email, but I’m sure that’s not the only reason. It’s also an easy way to share files across different computers. You can share a folder on your mac through a network connection and have it appear on all of your computers.
It’s not just a mac-based file sharing thing. Macs even have a built-in DNS server. If you set up your mac to have a domain name, you can even use it to point your web address to your mac. And that can be a huge pain to deal with if you have a lot of files of different sizes that you want to share. So I don’t use mac addresses for domain names.
The problem is that if you are using a mac to share files with other macs, your mac can have a lot more than one file. I know because I am. Many Macs, Windows machines, and even iPhones are able to share files over the local network. You can even share a folder or document by using a UNC path. That means that you can have a folder on your mac, say Documents, and any Mac that is connected to your network can see the Documents folder.
That is the issue. Not all Macs are able to share the same network files as PCs. As a result, most Macs either can’t share the local network or they can’t share the network with Windows machines. In its latest incarnation, Mac OS X 10.5.4 can only share one file at a time per computer. This means that if you have a folder on your mac called Documents, that only your Mac can see.
Yeah, it’s a little confusing because the official Mac OS X 10.5.4 changelog says that Macs can share network files. As I understand it, that’s still true, but it doesn’t mean that they can see all of the files on your Mac.
