If the DNS query is successful then the IP address will be reported in the

previously activated. In this case the context is deactivated after the DNS
query.
Note: <IP address> is in the format: xxx.xxx.xxx.xxx
AT#QDNS=? Test command returns the OK result code.

10..1200 - hundreds of ms (factory default value is 600).
Note: this time-out applies only to the time that the TCP stack waits for the
CONNECT answer to its connection request.

query (if the peer was specified by name and not by address) is not counted
in this time-out.
AT#SKTCT? Read command reports the current TCP connection time-out.
