Third Concept: Static Ip Versus Dhcp Operation - Tascam SX-1 Release Note

The address itself is comprised of four bytes of data, each one containing three numbers. Each group
of three numbers acts as a different part of the address.
For instance, imagine the address of your home was:
This address is actually made up of four different groups. Reading them backwards, the groups are:
Which state in your country you live in (CA — California), which city in your state you live in (Los
Angeles), which street in your city you live on (Maple Drive), and finally which house on your street
you live in (35).
If you substituted numbers for each of the groups - and also their possible number of components - in a
network address, you might get something like this: 031:001:200:035.
The first byte refers to the address s specific US state (California was the 31
second refers to the city in California (I have no idea which was first, so I chose 001). The third refers
to the specific street in Los Angeles (I chose a random number that would refer to Maple Drive), and
the fourth and final byte refers to the house number (35).
It should make sense then, that if any of the state, city, or street numbers were wrong, the mail could
not be delivered.
Here s the important concept to understand: between computers on a network, in general the first
three groups of numbers must match, while the fourth group must be at least one number away
from all of the other machines.
An example of a common choice for a LAN (Local Area Network — meaning a network that is closed,
and only exists on local machines) address might be 192.168.1.2 . Other machines on the same
network would have the value of the last byte at least one digit away from the others (while the first
three remained the same), so they might be set to 192.168.1.3 , or 192.168.1.4 , etc.
This is like placing all the machines on the same street in our previous example - so that they re all in
the same neighborhood - only with different house numbers.

Third concept: Static IP versus DHCP operation

A static IP address refers to an address that is permanent — meaning that it never changes. If you
manually enter an IP address for the SX-1, it is static. This means that from reboot-to-reboot, the IP
address is always the same.
DHCP stands for dynamic host control protocol , with the most important word in the title being
dynamic - meaning that it changes - and thus is not static. When using DHCP, another device assigns
the SX-1 an IP number when it boots up. The number assigned is chosen from a range of possible
values, and it can change from connection to connection. The device that assigns the number is most
likely a network router or a switch, which are devices that are designed to sort and deliver data packets
to their destinations among the network, and often interface with larger networks and WAN s (Wide
Area Network — not contained on local machines).
When using Static IP s all of the communication information must be manually entered, because it
never changes. When using DHCP, the router or switch assigns all of the addresses and subnets, which
means that the IP address, subnet mask and gateway fields will be grayed out (though they will still
show the IP, subnet, and gateway once they receive them).
