Have you had to deal with DNS and DHCP?

Yes, I have worked with DNS and DHCP.

DNS (Domain Name System) is a system that translates domain names into IP addresses. When working with DNS, it is often necessary to:

• Configure records (A, CNAME, MX, etc.) for proper name resolution.
• Diagnose name resolution issues using utilities like nslookup, dig.
• Set up local DNS servers or caching to speed up access.

DHCP (Dynamic Host Configuration Protocol) is a protocol that automatically assigns IP addresses and other network parameters to clients on a network. In working with DHCP, it is common to:

• Configure DHCP servers to assign addresses within a specified range.
• Define lease parameters, reserve addresses by MAC addresses.
• Diagnose issues with clients obtaining IP addresses.

Example: When deploying a local network at a company, I configured a DHCP server so devices automatically received IP and DNS servers, and I also set up DNS records for internal services so users could access them by name.
