// Command = new RelayCommand(() => this.ChangeToServer(addresses[i].ToString())
// can't be executed, due to access to modified closure (the variable i) within lambda expression.
// Normally you can create a new local variable (var i1 = i) and use this local variable within the lambda expression
// -> no access to modified closure anymore.
// But this doesn't work here, too.
// You can't specify a index of the addresses list within the "Command" - lambda expression here.
// It has to be a constant value.
//
// This method is a pseudo-workaround (very, very ugly).
// Wasn't able to find another solution at this point.
// It stops working, once AddressResolving.GetIpv4Addresses() returns more than 5 elements.
// ToDo find another solution to add the ip addresses to the AquireServerButton, with some working loop
