Private IP addressing and network interfaces in depth

الـ Private IP والـ Network interfaces بالتفصيل

What you will be able to do

• Explain how Azure DHCP assigns private addresses and which five addresses every subnet reserves.
• Choose between dynamic and static allocation and predict when an address is kept or released.
• Explain why IP addresses are never configured inside the guest OS, recognise the symptoms and recover a VM that was broken this way.
• Add secondary IP configurations and multiple NICs, and configure them inside Windows and Linux.
• Use IP forwarding, accelerated networking, Standard public IPs with DNS labels, and read effective routes and security rules.
