IP address 194.176.45.46/27 tentukan: A. Jumlah subnet B. Subnet mask C. Jumlah host D. IP network E. IP broadcast F. IP address yang valid

194.176.45.46/27

subnetmasknya :
/27 = 11111111.11111111.11111111.11100000

subnet = 2^jumlah 1
jadi (2^3 = 8 subnet)

host = jumlah 0^2 - 2 
jadi (2^5)-2 = 32 - 2 = 30 host

Network : 194.176.45.0
Host valid : 194.176.45.1 - 194.176.45.30
Broadcast : 194.176.45.31
