A method of a first DNS which can update server information in real time without necessarily using a TTL (Time To Live) by recording a network address of the first DNS, which has previously obtained server address information from a second DNS, in a notification list, by the second DNS, and transmitting the changed information from the second DNS to the first DNS recorded in the notification list when the previously obtained/requested server address changes, and updating the server address by the first DNS as provided by the second DNS. A DNS updating server address method may further include providing a first DNS with server address information corresponding to a domain, recording a network address of the first DNS in a notification list, corresponding to the domain and/or the server address information, and transmitting a changed server address information to the first DNS based on the notification list.

Apparatus and method for removing the influence of microwave noise, without any shielding parts, thus increasing the reliability of detected humidity information. According to the invention, the cumulative difference of humidity values sensed by a humidity sensor is calculated for each half period of a commercial alternating current frequency, oscillating and non-oscillating terms of a magnetron are determined by comparing the calculated cumulative differences with each other, and the humidity-sensed values obtained during the determined non-oscillating terms of the magnetron are used as humidity information for automatic cooking control. In order to even further remove the influence of the microwave noise, the humidity sensor may include capacitors for bypassing the microwave noise introduced into the sensor.

An apparatus for and a method of automatically heating foods in a microwave oven, capable of heating foods at an optimum state even when foods are to be continuously heated, by determining an ambient temperature from a variation in temperature of air introduced in a heating chamber through an air inlet port, determining a temperature increment in a heating chamber of the microwave oven and an amount of food, based on the determined ambient temperature, determining a primary heating time and an additional heating time, based on the determined temperature increment, and then determining an additional heating time, based on the determined food amount. As a result, it is possible to achieve an improvement in cooking performance. In addition, over-heating of the good is avoided, thereby enabling a reduction in electric power consumption and a reduction in cooking time.
