A human being can be identified differently: name on a birth certificate and Aadhaar card number. Similarly, an Internet host (e,g., any device that is connected to the Internet, e.g., laptop, mobile phone etc.) can be identified using hostname or IP address. Within a given context, one identification may be more appropriate than another. Host names are mnemonic, and therefore, we can remember them easily. But it has some disadvantages: (i) From the hostname, we can not accurately locate the host on the Internet (ii) Since a hostname consists of variable length alphanumeric characters, they would be difficult to process by routers.
