Part 3 – AT Commands for Wi-Fi DevicesChapter 10 – IP AT Commands for the SocketWireless Wi-Fi

#IPRELEASE – Release a DHCP Address Assigned by the Server

Description:	In order to gracefully release a DHCP address assigned by the server, the module should issue a
	command of DHCPRELEASE.
Syntax:	AT#IPRELEASE
Response:	AT#IPRELEASE returns OK

#IPRENEW – Renew the DHCP Information from the Server

Description:	The DHCP client can renew the DHCP information from the server. On completion of lease time,
	the DHCP client will automatically renew the DHCP information. Before that, if the client wants to
	renew the information, it can use this command.
Syntax:	AT#IPRENEW
Response:	AT#IPRENEW returns OK

#IPQUERY – Give a Domain Name

Description:	Sends a query to the DNS server to resolve the name
Syntax:	AT#IPQUERY=<Host Name>
Response:	OK
Values:	Host name in alpha-numeric string format. Example: www.google.com. No default.

#IPRESOLV – Is There a Connection with DNS or Not

Description:	If the DNS client is successful in resolving the host name, this command shows the IP address of
	the resolved host name. If the DNS client fails to resolve, it shows error message.
Syntax:	AT#IPRESOLV=<Host Name>
Values:	Host name in alpha-numeric string format. No default.

S0= – Automatic Answer

Description: Sets automatic answering of TCP or UDP connections.
