DNS & DHCP Administration Course in Doha, Qatar

The DNS & DHCP Administration course in Doha, Qatar focuses on the two core services that every user and application relies on without noticing, until they fail. Participants learn how recursive and authoritative DNS resolution works, how zones, delegation and record types such as A, AAAA, CNAME, MX, PTR, SRV and TXT are managed, and how DHCP leases addresses through the DORA exchange of discover, offer, request and acknowledge. The course explains how both services are planned together so that addressing, naming and directory services stay consistent across an organization.

Learning is practical, with labs on Windows Server DNS and DHCP and on the widely used open-source BIND DNS server. Learners create forward and reverse lookup zones, configure scopes, reservations, options and DHCP relay, set up DHCP failover, and use nslookup, dig and packet captures to diagnose faults. Security topics include DNSSEC, split-horizon DNS, DHCP snooping and protecting against rogue servers. The course can be delivered as an in-house program for organizations, built around the client's own directory and addressing environment.

By the end of this course, participants will be able to:

• Explain recursive, iterative and authoritative DNS resolution and caching behavior

• Create and manage forward and reverse zones with common DNS record types

• Configure DHCP scopes, reservations, options and relay for multiple subnets

• Implement DHCP failover and DNS redundancy for high availability

• Apply DNSSEC, split-horizon DNS and DHCP snooping to improve security

• Troubleshoot name resolution and addressing faults with nslookup, dig and packet captures

This course is intended for IT staff who run or support core network services.

• Systems and network administrators

• Windows Server and Active Directory administrators

• IT support and service desk engineers handling escalations

• Infrastructure engineers responsible for IP address management

• Security staff monitoring DNS activity

Module 1: How DNS Works

• Recursive and iterative queries, caching and TTL

• Authoritative servers, delegation and glue records

• Common record types: A, AAAA, CNAME, MX, PTR, SRV, TXT

Module 2: Administering DNS Servers

• Forward and reverse lookup zones

• Primary, secondary and Active Directory-integrated zones

• Zone transfers, forwarders and conditional forwarding

• Configuring zones in Windows Server DNS and BIND

Module 3: DHCP Configuration

• The DORA process and lease lifecycle

• DHCP failover and split-scope designs

Module 4: Securing DNS and DHCP

• DNSSEC signing, keys and validation basics

• Split-horizon DNS for internal and external names

• DHCP snooping and rogue DHCP server detection

• DNS logging and filtering against malicious domains

Module 5: Troubleshooting and IP Address Management

From digital government portals to banking platforms and hospital systems, almost every service in Qatar depends on reliable name resolution and automatic addressing. As organizations add cloud services, branch offices and connected devices, poorly managed DNS and DHCP quickly cause outages and security gaps. Skilled administrators help keep these foundations stable and secure, in line with general guidance from Qatar's National Cyber Security Agency, and support the dependable digital infrastructure that Qatar National Vision 2030 aims to build.
