To identify or not to identify: the MAC address.
The so-called MAC address is a unique identifier assigned all network devices. The MAC ad-
dress is permanently assigned to the device and cannot be modified. They can therefore be
used to configure routers to permit only devices with specific MAC addresses to access the
network or the Internet. In such a case, it will be necessary to configure the router with the
NOXON's MAC address so that it will be able to establish a network connection. The address
can be found on a label on the back of the NOXON audio.
Sometimes required: a fixed IP.
Under certain circumstances, it can be useful for a device to always have the same address.
Most networks these days are set up to assign the so-called IP address—the identifier for the
TCP/IP protocol—dynamically. In other words, the first time a device connects, the so-called
DHCP server assigns it a valid IP address which the device will keep as long as the address is
not needed elsewhere. This occurs completely automatically, without the user's knowledge. If
a network is based on static IPs—i.e. fixed addresses, rather than dynamically assigned
ones—there will generally be a precise set of rules governing the addresses that can be as-
signed. And our friend the NOXON also has such an IP address. If the network requires a fixed
address, the rules for assigning them must be known. But once again, a fixed IP is really the
exception; generally, everything happens automatically.
