Task $2$: Subnetting and IP Addressing with VLSM

Using Variable Length Subnet Masking $($VLSM$),$ allocate IP addresses to each branch's LAN, servers, and links. Incorporate the provided IP address ranges and subnet the addresses efficiently to accommodate the different user sets. Ensure seamless connectivity between Tokyo, other Japanese cities, and Sydney. Your design should maximize IP address utilization while allowing for future growth.
