What is Network Address Translation (NAT)? Network Address Translation (NAT) is a method used in networking to modify network address information in the header of IP packets while they are in transit across a traffic routing device. The primary purpose of NAT is to enable multiple devices on a local network to access the internet using a single public… Read More »

What is IP Address Route Summary? IP Address route summation; which is also known as route aggregation, is the process routers use in advertising volume or set of IP addresses as a single address with a shorter subnet mask (CIDR). Route summarization allows engineers to configure a routing protocol so that it advertises one route, replacing several smaller… Read More »
What is IPv6 ACLs? There are similarities in the operation and configuration of IPv6 ACLs and its predecessor IPv4 ACLs. If you are familiar with the basic operation and configuration of the IPv4 access controls list, you will find IPv6 ACLs easy to understand and configure too, the only difference is just the IPv6 addressing. An IPv6 Access… Read More »
IPv6 Address Expression and Examples Unlike the 32-bit with four 8-bit fields of IPv4 address, separated by dots; IPv6 processes a larger, 128-bit and uses colons to separate its 16-bit hexadecimal entries. Below explains how to shorten the IPv6 address: Lets use the IPv6 address: 2041:0000:130F:0000:0000:07C0:853A:140B. The Leading zeros in a field are optional. That means: the field 07C0 equals 7C0, and… Read More »
