How do you work with network technologies and tools?

Working with network technologies and tools in DevOps involves several key aspects:

• Network monitoring and diagnostics: Using tools like ping, traceroute, netstat, tcpdump to check availability and analyze network traffic.
• Configuration and management of network services: Working with DNS, DHCP, VPN, configuring firewalls (e.g., iptables or firewalld), managing load balancers.
• Automation and infrastructure as code: Using Ansible, Terraform, or other tools to automate the configuration of network components.
• Containerization and orchestration: In Kubernetes and Docker, network plugins and settings (CNI) are important for ensuring communication between containers.

Example of using ping to check server availability:

ping -c 4 example.com

Thus, I combine basic network utilities with modern automation tools for effective management of network infrastructure.
