Lookup
With Lookup you can search for information about OUIs (Organizationally Unique Identifiers) and ports.
OUI
On the OUI tab, you can search for the manufacturer of a network interface card (NIC) by entering the first 24 bits of the MAC address. You can also search by vendor name to get all registered MAC addresses of the vendor.
The OUI (Organizationally Unique Identifier) is a 24-bit number assigned by the IEEE Registration Authority to identify network interface card manufacturers. It forms the first 24 bits of a MAC address.

Port
On the Port tab, you can search for a port number to get information about the service and the protocol used by the port. You can also search by service name to get all registered port numbers of the service.
A port is a logical construct that identifies a specific process to which network traffic is to be forwarded. Ports are identified by a 16-bit number, known as a port number. Port numbers range from 0 to 65535, but only port numbers 0 to 1023 are designated as well-known ports. Well-known ports are those registered with IANA for common services such as HTTP (port 80), HTTPS (port 443), FTP (port 21), and SSH (port 22).
