Abstract:
1. A computer implemented method for inferring address and subnet relationships, the method comprising: identifying, by a processor, a first address associated with a subnet; determining, by a processor, when a portion of a second address matches a portion of the first address; wherein the first address includes a prefix part and a non-prefix part; and the second address includes a prefix part and a non-prefix part; determining, by a processor, when lengths of the prefix parts of the first and second addresses are equal based on a first stored prefix length value corresponding to the first address and a second stored prefix length value corresponding to the second address; inferring, by a processor, a relationship between the second address and the subnet when the portion of the second address matches the portion of the first address, and the first stored prefix length value and the second stored prefix length value are equal; converting the first address to a binary bit string; and truncating the binary bit string to the length of the prefix part of the first address to form the portion of the first address; wherein the determining when the portions of the first and second addresses match comprises performing an SQL wildcard match for the second address using the truncated binary bit string.
