Abstract: Embodiments herein describe tokenizing a data sequence to perform a wildcard lookup. For example, a network device (such as a NIC or a switch) can receive a data sequence (e.g., an IP address, Uniform Resource Locator (URL), domain name, etc.) which can be broken down into separate tokens. After identifying a first token, the network device can search a wildcard lookup table to determine a first entry in the table that matches the first token. Assuming there is a match, the network device can identify an action associated with the entry. If the action is to continue with the search, the network device can then retrieve a key from the entry which it then combines with a second token in the data sequence to again search the wildcard lookup table.
