static ip question

So I have the XR 450 gaming router.

 

I am setting it up with my ps4 and wondering if I set a static ip address, which is under the lan settings, will it apply to non lan wifi connections as well?

 

Thank you

    Reserving an address for a specific device works both for LAN and WiFi devices. If you add a reserved address for a device, it'll always get the same IP from the DHCP no matter if connected with a cable or wirelessly

     

    Just make sure you use the correct MAC address. If a device has both wired and wireless capabilities, it'll have 2 different MAC addresses, one for the wired and one for the WiFi

  • Yes, and it's not a static address but a DHCP reserved one, based on the device's MAC address. Static addresses are set on the device(s) itself, not in the router

      considering i want to set up a port forwarding system for my ps4, are these functionally the same thing or i should i still set up a static ip on the ps4?

       

      if i set up a static ip, is there any reason for this reserved ip?

       Terminology: A "static" address is configured on the device itself.
    What you configure on the (DHCP server on the) router is a reserved
    dynamic address, not a static address.

       What is the actual problem which you are trying to solve?


       A network "connection" does not have an IP address; a network
    interface does.  Apparently, your "my ps4" has two network interfaces,
    one wired (Ethernet), and one wireless.

     

       Address Reservation reserves a particular IP address to be associated
    with a particular MAC address.  Normally, every network interface in
    your LAN has its own (locally) unique MAC address.  Reserving an IP
    address for one network interface (specified by its MAC address) does
    not automatically reserve that IP address for any other network
    interface (which should have its own, different MAC address), even if
    both those interfaces are in the same box ("my ps4").

     

       You can try it, but I'd guess that the router won't let you reserve
    the same LAN IP address for two different MAC addresses.  If that's what
    you're trying to do.


       Note that, strictly speaking, your "my ps4" does not have an IP
    address.  A network interface in your "my ps4" can have an IP address.
    If there are two network interfaces in your "my ps4", then each one can
    have its own IP address.  (I'd bet that each one has its own MAC
    address.)  Trying to give the same IP address to both network interfaces
    in your "my ps4" is more likely to cause trouble than not.

      i reserved an ip address under the lan settings for my ps4 based on it's mac address.

      the issue is that this was under lan settings on the router. that is why i am not sure if it will apply to the wireless connection i am using with it.

      because it was under lan settings...is the thing.

      also i know i can set a static ip on the ps4 interface.

      my question is if that is necessary or if the dhcp i set up under lan settings will have the same effect.

      i am only using my ps4 with this router, so that is why i am thinking the dhcp settings alone might work for, it in terms of setting up port forwarding
