FAQ
CIDR notation kya hai?
/24 jaisa notation batata hai ki kitne bits network ke liye reserve hain. /24 = 255.255.255.0 subnet mask ke barabar hai, jisme 256 addresses hoti hain (254 usable).
Network aur broadcast address alag kyun hote hain usable range se?
Har subnet ka pehla address (network address) subnet ko identify karta hai, aakhri (broadcast) sabko message bhejne ke liye reserved hai — dono devices ko assign nahi kiye ja sakte.
Ye networking students/sysadmins ke liye kyun useful hai?
Subnetting manual calculation error-prone hai — ye tool turant sahi values deta hai IP planning, VLAN setup ya exam preparation (CCNA jaisi certifications) ke liye.
