4.3 Technical Reference
The following section cont ains additional technical inform ation about t he LTE Device feat ures
described in this chapt er.
Encapsulation
Be sure t o use t he encapsulation m et hod required by your I SP. The LTE Device support s t he
following m et hods:
IP Address Assignment
A static I P is a fixed I P t hat your I SP gives you. A dynam ic I P is not fixed; t he I SP assigns you a
different one each t im e. The Single User Account feature can be enabled or disabled if you have
eit her a dynam ic or stat ic I P. However the encapsulation m et hod assigned influences your choices
for I P address and default gateway.
DNS Server Address Assignment
Use Dom ain Nam e System ( DNS) t o m ap a dom ain nam e to it s corresponding I P address and vice
versa, for instance, t he I P address of ww w.zyxel.com is 204.217.0.2. The DNS server is ext rem ely
im port ant because wit hout it, you m ust know t he I P address of a com puter before you can access
it .
The LTE Device can get t he DNS server addresses in the follow ing ways.
1 The I SP tells you t he DNS server addresses, usually in t he form of an inform ation sheet, when you
sign up. I f your I SP gives you DNS server addresses, m anually enter t hem in the DNS server fields.
2 I f your I SP dynam ically assigns t he DNS server I P addresses ( along wit h t he LTE Device’s WAN I P
address) , set t he DNS server fields t o get t he DNS ser ver addr ess from t he I SP.
