The possible solution in DHCP_MSGOFFER

			fprintf(stdout, "{\"msg\":\"DHCP offer details\","
				"\"result\":\"info\","
				"\"result-type\":\"offer\","
				"\"result-ip\":\"%s\",",
				get_ip_str(dhcph_g->dhcp_yip));
			fprintf(stdout, "\"result-next-srv\":\"%s\"",
				get_ip_str(dhcph_g->dhcp_sip));

For the DHCP_MSGACK

                        fprintf(stdout, "{\"msg\":\"DHCP ack details\","
				                "\"result\":\"info\","
				                "\"result-type\":\"offer\","
				                "\"result-ip\":\"%s\",",
				                get_ip_str(dhcph_g->dhcp_yip));
			            fprintf(stdout, "\"result-next-srv\":\"%s\"",
				                get_ip_str(dhcph_g->dhcp_sip));
