To set up an IP-CORE network, you mainly use core and distribution routers, all configured with IPv6 to handle network traffic and services.

Some Windows versions (like Windows 10 Home) don’t fully support DHCPv6 and use SLAAC to get IPv6 addresses automatically. this doesn’t stop IPv6 from working.

It just means only Pro, Enterprise, and Server editions fully support DHCPv6 with extra control and management features.

The IPv4 base header is 20 bytes long without options, and can extend up to 60 bytes if options are included.

The IPv4 base header has 10 mandatory fields, and together they add up to 160 bits.
1 byte = 8 bits then 160 bits / 8 bits = 20 bytes.

So, IPv4 base header = 20 bytes (160 bits) without options.

CIDR and VLSM save IP addresses but make network setup and management more complicated.
