Abstract
A method and computer product for automatically generating an IP network address that facilitates simplified network connection and administration for small-scale IP networks without IP address servers, such as those found in a small business or home network environment. First, a proposed IP address is generated by selecting a network identifying portion (sometimes known as an IP network prefix) while deterministically generating the host identifying portion based on information available to the IP host. For example, the IEEE 802 Ethernet address found in the network interface card may be used with a deterministic hashing function to generate the host identifying portion of the IP address. Next, the generated IP address is tested on the network to assure that no existing IP host is using that particular IP address. If the generated IP address already exists, then a new IP address is generated, otherwise, the IP host will use the generated IP address to communicate over the network. While using the generated IP address, if an IP address server subsequently becomes available, the host will conform to IP address server protocols for receiving an assigned IP address and gradually cease using the automatically generated IP address.
