Packet Domain Commands
HL7518 and HL7548
<primary DNS>, <secondary DNS> Strings representing the DNS addresses and
given as dot-separated numeric (0 – 255) parameters in the form of:
a1.a2.a3.a4 for IPv4,
a1.a2.a3.a4.a5.a6.a7.a8.a9.a10.a11.a12.a13.a14.a15.a16 for IPv6 and
a1.a2.a3.a4.a5.a6.a7.a8.a9.a10.a11.a12.a13.a14.a15.a16.a17.a18.a19.a20 for IPv4v6. (a1
to a4 here represents IPV4 and a5 to a20 represents IPv6)
The DNS address is by default "0.0.0.0" which is not a valid address.
Note that IPv6 address obtained on LTE will be prefixed with a constant 8-byte address
"FE.80.00.00.00.00.00.00" if the network has not provided any.
Notes
IPv6 is not supported in the HL7548.
