There's nothing strange here: the contents of ip_addr_t needs to be in network byte order and the sntp client calls a function that returns the correct byte order.

OK, to clarify that: to get the ip_addr_t that is used to configure my network interface I have to do the following for IP, gateway and netmask:

    ipaddr_aton(c, &globalConfig.ip);

    globalConfig.ip.addr=htonl(globalConfig.ip.addr);

For getting the ip_addr_t for the SNTP-server this is not neccesary, there a plain

    ipaddr_aton(c, &globalConfig.sntp_ip);

works (without the need to do a htonl() on the addr member).

So this is different depending on the usage of the IP - for what reason ever.
