4.3 Technical Reference
The following section contains additional technical information about the LTE Device features
described in this chapter.
Encapsulation
Be sure to use the encapsulation method required by your ISP. The LTE Device supports the
following methods:
IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a
different one each time. The Single User Account feature can be enabled or disabled if you have
either a dynamic or static IP. However the encapsulation method assigned influences your choices
for IP address and default gateway.
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice
versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely
important because without it, you must know the IP address of a computer before you can access
it.
The LTE Device can get the DNS server addresses in the following ways.
1
The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2
If your ISP dynamically assigns the DNS server IP addresses (along with the LTE Device’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
