Disclosed is a packet-switched communication apparatus receiving and forwarding messages which are used to obtain an address corresponding to a domain name assigned to a device connected to a network from the domain name and to obtain such a domain name from the address. Some of the structures and methods relate to a Deeply Depleted Channel design, allowing CMOS based devices to have a reduced \u03c3VT compared to conventional bulk CMOS and can allow the threshold voltage VT of FETs having dopants in the channel region to be set much more precisely. The flash memory 303 includes an authentication memory 332 and a non-authentication memory 331.
