Assigning IP addresses to all the end devices in the network is the main task of the DHCP. So called DHCP server is assigning the IP addresses and terminating those when they are not required anymore. DHCP server stores and modifies information about IPs that already are in use, that will be available soon, and which are not allowed. In ...
This article is intended to show difference between IPv4 and IPv6. It introduces the list of new features that IPv6 is offering.
When you see IPv6 address it is easy to notice how differently it is written. While IPv4 is written in a form of four decimal numbers separated by a period, the IPv6 is having eight hexadecimal numbers separated by ...
The name for the TCP/IP protocol IGMP can stand either for Internet Group Management Protocol or Internet Group Multicast Protocol. It is used for sending exact same packets of data to multiple nodes. Unlike broadcasting, the group of recipients can be defined. Although most of data is sent on P2P basis in the network, IGMP is providing multicasting that uses ...
What is Subnet Mask, Types of Subnet Mask? Why you should care? Well, every device in the IPv4 network has its own subnet mask, that defines which subnet device it belongs to. Subnet mask is a 32-bit number that is being combined with device IP for identification of its subnetwork.
Subnet mask can be written either in binary (111111.111111.111111.000000) or decimal ...
This protocol is necessary for ensuring that data has been successfully received by the recipient node. ICMP reports to the sender on successful or unsuccessful data delivery. It indicates reason for data delivery failure like:
TTL (Time To Live) expiry
Data destination reach failure
Network congestion
ICMP provides failure information, that might be very useful for problem troubleshooting, but it does not solve any ...
What is ARP (Address Resolution Protocol)? This protocols main purpose is to identify network nodes MAC address using its IP. ARP creates database of discovered nodes in the network and saves it on local machine for future use.
Whenever one node of the network needs to know some other nodes MAC address, it broadcasts the ARP message to the network. Message contains ...
