1. A method for avoiding dynamic domain name system (DNS) collisions comprising:

  • storing a first location associated with a primary location of a first client device associated with a first dynamic DNS user, a second location associated with a primary location of a second client device associated with a second dynamic DNS user, and a third location associated with a primary location of a network;

    receiving, from the first client device associated with the first dynamic DNS user, a first notification indicating an Internet Protocol (IP) address assigned to the network, wherein the first client device is connected to the network;

    receiving, from the second client device associated with the second dynamic DNS user, a second notification indicating the IP address assigned to the network, wherein the IP address received from the second client device is the same as the IP address received from the first client device, and wherein the second client device is connected to the network;

    determining a most likely owner of the network between the first client device and the second client device based on the first location, the second location, and the third location, wherein ownership of a network determines which dynamic DNS user the network shall be attributed to; and

    applying a content filtering policy associated with the first client device to at least one attempt to access a network resource via the network when the first client device is determined to be the most likely owner.
