    OK, let's try
    I would like to find a way allowing several siteId in a configuration.
    The system (a NodeMcu8266) would try them in sequence.
    For that I am trying:

    struct netw
    {
    char *MXWifi;/*ssid*/
    char *YYYZY; /*passwd*/
    const char *MyIp; /*ip adress*/
    struct netw *next;
    };

    struct netw prem = {"AAACCCCCC","xvdfgghs","192,168,1,32"};
    struct netw seco = {"Orange-aaa","7XyZzR","192,168,0,32"};

    struct netw *current;

    In setup()

    IPAddress local_IP(MYIpad);
    IPAddress gateway(MYGatew);

    DoConnect();


    in
    void Doconnect() {

    while(1) {
    Serial.println(current->MXWifi);
    Serial.println(current->YYYZY);
    Serial.println(current->MyIp);

    // IPAddress local_IP(current->MyIp);
    Serial.println("-------------------");

    if (current->next != &prem) {
    current = current->next;
    } else {
    current = &prem;
    break;
    }


    }

    Compilation fail on current->MyIP
    Doesn't' accept 198,162... nor 198.162...
    Type IPAdress seem to only accept:

    #define MYIpad 192,168,0,32

    Typically Arduino??

    Many thanks in advances

    I have never seen anything using commas in IP addresses instead of
    periods. It is not an arithmatic number, so those are not decimal
    points, so I can't imagine anyone, ever, anywhere needing to translate periods to commas or vice versa in IP addresses. If your library does do that, I'd be looking for a different library.

    It is actually how they do it: https://www.arduino.cc/reference/en/libraries/ethernet/ipaddress/
    however it's a constructor which accepts four arguments, being the four 8
    bit chunks of the IPv4 address: https://github.com/esp8266/Arduino/blob/master/cores/esp8266/IPAddress.h#L70 https://github.com/esp8266/Arduino/blob/master/cores/esp8266/IPAddress.cpp#L38

    Hence you can do:
    IPAddress alice(127,0,0,1);

    which creates an instance of the IPAddress class pre-initialised with
    the four octets from 127.0.0.1

    But, looking at that code, I think you need fromString() to parse the string
    in a "127.0.0.1" format, ie:

    IPAddress local_ip();
    local_ip.fromString(prem.MyIp); // sets local_ip to address in MyIp

    - which is more time consuming and error prone than the constructor which
    just accepts (127,0,0,1) as arguments.

    Run a local DNS (named, kea or knot) - I'm running named.
    Set it up to be authoritative for your local LAN and to pass all other requests to the global root DNS servers.


    I think I will start a HOTSPOT on a Raspberry (maybe a Zero ) with
    dnsmask (dns and DHCP ) it also une local host table, and so be rid of
    the problem. But I need to use an extra system for this wich is...

    There is the problem -> const char *MyIp; /*ip adress*/

    In Arduino IPAddress class is defined (in IPAddress.h) as:

    IPAddress();
    IPAddress(uint8_t first_octet,
    uint8_t second_octet,
    uint8_t third_octet,
    uint8_t fourth_octet);
    IPAddress(uint32_t address);
    IPAddress(const uint8_t *address);


    So the line

    #define MYIpad 192,168,0,32

    defines only a place holder 'MYIpad' and this satisfies the second
    definition above: IPAddress(MYIpad) -> IPAddress(192, 168, 0, 32)

    You have to give the class initialiser 4 octets

    Or you make a unsigned integer of 32 bits from the 4 octets, to store in
    your struct...

    Hope this helps

    How much bandwidth do you need ? Do you have a managed switch ? If
    the answers are favourable then you could run two VLANs out of the Pi and
    use the managed switch to present them to separate ports without the
    tagging. I did this years ago using an original Pi as a router.

    The OP has an ESP8266 running the Arduino platform. That isn't a Raspberry
    Pi, isn't running Linux, they don't need to run extra servers on a Raspberry
    Pi to simply set an IPv4 address in their ESP8266, which is something that every machine in the last two decades needs to do.

    OP, if you use wifiMulti, it already does DHCP for you. From that link
    above, see the log:

    connected with sensor-net-1, channel 1
    dhcp client start...
    ip:192.168.1.10,mask:255.255.255.0,gw:192.168.1.9

    According to the source: https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/examples/WiFiMulti/WiFiMulti.ino
    the IP is printed via:

    Serial.println(WiFi.localIP());

    So presumably that gives you the local IP, should you need it for further
    use.

    Your home AP handles DHCP requests. Your ESP will get local IP.
    Than your AP will send all your outgoing requests from its own address.
    In case you need to access your ESP from the net you will have to
    do port forwarding from your AP. That way you will be able to access your
    ESP from the net.

    If you need to know your AP's dynamic IP address you can use some kind
    of external service... I have something like this for sending my IP: https://mudrac.ffzg.hr/~nlazic/ip.php?whatever_text&1
    and for getting my IP I use: https://mudrac.ffzg.hr/~nlazic/ip.php?whatever_text

    You just have to send the first line from your ESP.
    Use the second line to get IP from yout AP to contact your ESP through
    port forwarding service on your AP.

    address. So I have to give IPAdresse local_IP(MyIpAd);
    MyIpAd is
    #define 192,168,0,111 in another file.

    You will be given local IP from your home Access point.
    Then sort out how to manage port forwarding on your AP.

    I think I will start a HOTSPOT on a Raspberry (maybe a Zero ) with

    That way you will again get the same functionality as with your AP

    The Raspberry should have a second ethernet access (cable or a second

    Zero has USB connection through four testpoints on the board. You can use
    those to connect to some USB HUB and connect anything you need.
    But you have to provide enough power to the USB HUB.
