What is Internet Protocol (IP)?
Feb 23rd
The Internet Protocol (IP) is the transmission mechanism used by the TCP/IP protocols. IP is an unreliable and connectionless datagram protocol. IP provides no error tracking or error checking. IP assumes the unreliability of the underlying layers and does its best to get a transmission to destination but without guarantee.
What is DNS (Domain Name space)?
Feb 23rd
Domain name space was designed to have hierarchical name space. The domain names are inverted-tree structure from root to top. The trees only have 128 levels. Root is levels 0 and top has 127.
Labels: Each and every node in the tree has label. Label is having maximum length 63 characters. The root label is a null string. DNS require that children of a node have different labels, which guarantees the uniqueness of the domain names.
