Final answer:
Dynamic Host Configuration Protocol (DHCP) is used to automatically assign IP addresses and related network configurations to devices on a network. DNS Security Extensions (DNSSEC) enhance the security of the DNS system by providing data integrity and origin authentication for DNS data.
Step-by-step explanation:
Dynamic Host Configuration Protocol (DHCP)
The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks. Its primary purpose is to automate the assignment of IP addresses, subnet masks, gateways, and other IP parameters.
When a device connects to a network, DHCP allows it to receive an IP address automatically, which is essential for communication within the network and to the internet.
DHCP ensures each device has a unique IP to avoid conflicts and can be assigned a range of other configurations that enable smooth network functionality.
DNS Security Extensions (DNSSEC)
DNS Security Extensions (DNSSEC) are a suite of Internet Engineering Task Force (IETF) specifications for securing certain kinds of information provided by the Domain Name System (DNS) as used on Internet Protocol (IP) networks.
It is a set of extensions to DNS which provide to DNS clients (resolvers) origin authentication of DNS data, authenticated denial of existence, and data integrity, but not availability or confidentiality.
