4.4 Technical Reference
The following section contains additional technical information about the LTE Device features
described in this chapter.
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice
versa. 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.
