IP header

An IP header is a prefix to an IP packet that contains information about the IP version, length of the packet, source and destination IP addresses, etc. It consists of the following fields: Here is a description of each field: Version – the version of the IP protocol. For IPv4, this field has a value […]

IPv6 routing protocols

Like IPv4, IPv6 also supports routing protocols that enable routers to exchange information about connected networks. IPv6 routing protocols can be internal (RIPng, EIGRP for IPv6…) and external (BGP).   As with IPv4, IPv6 routing protocols can be distance vector and link-state. An example of a distance vector protocol is RIPng with hop count as […]

HTTP & HTTPS

HTTP (Hypertext Transfer Protocol) HTTP is an client-server protocol that allows clients to request web pages from web servers. It is an application level protocol widely used on the Internet. Clients are usually web browsers. When a user wants to access a web page, a browser sends an HTTP Request message to the web server. […]
