Understanding Dynamic Host Configuration Protocol

Understanding Dynamic Host Configuration Protocol

Posted on August 18, 2022October 2, 2023 by Adeniyi Salau

The Dynamic Host Configuration Protocol (DHCP) for IPv4 service automates the assignment of IPv4 addresses, subnet masks, gateways, and other IPv4 networking parameters. This is referred to as dynamic addressing. The alternative to dynamic addressing is static addressing. When using static addressing, the network administrator manually enters IP address information on hosts.   When a…

The Truth About Domain Name Service

Posted on August 18, 2022October 2, 2023 by Adeniyi Salau

The webservers that we so often connect to using names like www⋅cisco⋅com, are actually reached by assigning IP addresses to packets. On the internet, these domain names are much easier for people to remember than an IP address such as 74.163.4.161. If Cisco decides to change the numeric address of www⋅cisco⋅com, it is transparent to…
