First log: No error.
Second log: Crashes.
Same concept. Different behavior.

Why does var survive but let doesn't? 🤔

Explanation:

In classful network addressing, a default Class B network block uses a 16-bit subnet mask of 255.255.0.0, which allocates the first two octets for the network portion and the last two octets for host devices.

The network identifier (or network address) is officially represented by setting all host bits in the address to binary 0, which clears out the last two octets to form 150.10.0.0.

In contrast, option A represents the directed broadcast address (all host bits set to 1), while options B and D represent assignable, valid host IP addresses within that specific network block.

C. 150.10.0.0.✅
