55.33.9.220.0010 is a numerical representation of an IP address, which identifies a device connected to a network. It's divided into four octets, each representing a different part of the address. The first octet, 55, is the network ID, while the remaining three octets are machine identifiers, which specify the device's exact location on the network. The last octet, 0010, is a subnet mask, which is used to determine which devices can access the network.
