medium📝 Analysis Q4 of 15
Step-by-Step Solution
Solution:
Step 1: Understand subnet mask and block size
255.255.255.192 means /26 prefix, block size = 256 - 192 = 64.Step 2: Find network block containing IP
Blocks start at 0, 64, 128, 192. IP 130 falls in 128-191 block.Final Answer:
Network address is 192.168.10.128 -> Option AQuick Check:
Network block for 130 = 128 [OK]
Quick Trick: Block size = 256 - subnet mask last octet [OK]
Common Mistakes:
MISTAKES- Choosing wrong block range
- Confusing network address with broadcast
- Ignoring subnet mask effect
