Abstract
An information processing apparatus that is capable of setting suitable IP addresses to a plurality of communication lines. A setting unit sets up IP addresses of the plurality of communication lines. A detection unit detects a use situation of an allocation function of the setting unit that allocates an IP address consisting of a predetermined network address. A decision unit decides whether the allocation function is used for setting an IP address of a communication line other than a predetermined communication line according to the use situation of the allocation function for setting an IP address of the predetermined communication line that is detected by the detection unit.
Claims8
An information processing apparatus that uses a plurality of network interfaces, the information processing apparatus comprising:
- at least one memory that stores instructions;
- and
- at least one processor that executes the instructions, the instructions, when executed, causing the information processing apparatus to:
- in a condition where an IP address is assigned to a first network interface among the plurality of network interfaces by using a first allocation method, prevent a use of the first allocation method to assign an IP address to other network interfaces of the plurality of network interfaces;
- and
- when assigning an IP address to one of the plurality of network interfaces in a condition where an IP address is assigned to none of the plurality of network interfaces by using the first allocation method, allow a use of the first allocation method to assign an IP address to the one of the plurality of network interfaces.
A control method for an information processing apparatus that uses a plurality of network interfaces, the control method comprising:
- preventing, in a condition where an IP address is assigned to a first network interface among the plurality of network interfaces by using a first allocation method, a use of the first allocation method to assign an IP address to other network interfaces of the plurality of network interfaces;
- and
- allowing, when assigning an IP address to one of the plurality of network interfaces in a condition where an IP address is assigned to none of the plurality of network interfaces by using the first allocation method, a use of the first allocation method to assign an IP address to the one of the plurality of network interfaces.
A non-transitory computer-readable storage medium storing a control program causing a computer to execute a control method for an information processing apparatus that uses a plurality of network interfaces, the control method comprising:
- preventing, in a condition where an IP address is assigned to a first network interface among the plurality of network interfaces by using a first allocation method, a use of the first allocation method to assign an IP address to other network interfaces of the plurality of network interfaces;
- and
- allowing, when assigning an IP address to one of the plurality of network interfaces in a condition where an IP address is assigned to none of the plurality of network interfaces by using the first allocation method, a use of the first allocation method to assign an IP address to the one of the plurality of network interfaces.
