Answers<\/h3>\n\n\n\n\n
How many bits have been borrowed from the last octet from the subnet mask?<\/strong><\/li>\n<\/ol>\n\n\n\n
The subnet mask given is 255.255.255.192<\/strong>. In binary form, this subnet mask is:<\/p>\n\n\n\n
\n
255 = 11111111<\/code><\/li>\n\n\n\n
255 = 11111111<\/code><\/li>\n\n\n\n
255 = 11111111<\/code><\/li>\n\n\n\n
192 = 11000000<\/code><\/li>\n<\/ul>\n\n\n\n
In the last octet (192<\/code>), we see that the first two bits are 1<\/code> and the remaining six bits are 0<\/code>. This means that 2 bits have been borrowed<\/strong> from the last octet.<\/p>\n\n\n\n\n
Is the address 192.168.10.192 a network address?<\/strong><\/li>\n<\/ol>\n\n\n\n
To determine if the address 192.168.10.192<\/code> is a network address, we need to check if the host portion is all zeroes. Based on the subnet mask 255.255.255.192<\/code>, we have:<\/p>\n\n\n\n
\n
Network portion: 192.168.10.192 (the first 26 bits are network bits)<\/li>\n\n\n\n
Host portion: The remaining 6 bits are used for host addresses.<\/li>\n<\/ul>\n\n\n\n
Since the address 192.168.10.192<\/code> has the last 6 bits set to 000000<\/code>, this is the network address<\/strong> for the subnet 192.168.10.192\/26<\/code>.<\/p>\n\n\n\n\n
How many sub-networks will there be?<\/strong><\/li>\n<\/ol>\n\n\n\n
The subnet mask 255.255.255.192<\/code> indicates that 2 bits have been borrowed<\/strong> from the last octet. The total number of sub-networks created by borrowing bits is calculated as:<\/p>\n\n\n\n
[ 2^2 = 4 \\text{ sub-networks} ]<\/p>\n\n\n\n
So, there will be 4 sub-networks<\/strong>.<\/p>\n\n\n\n\n
Is the address 192.168.10.190 a broadcast address?<\/strong><\/li>\n<\/ol>\n\n\n\n
The broadcast address for a subnet is the address where the host portion is all 1s<\/code>. For the subnet 192.168.10.192\/26<\/code>, the broadcast address would be 192.168.10.255<\/code>. The address 192.168.10.190<\/code> is not<\/strong> the broadcast address.<\/p>\n\n\n\n\n
How many IP host addresses will be in each sub-network?<\/strong><\/li>\n<\/ol>\n\n\n\n
Each subnet has 6 bits for host addresses<\/strong>, as determined from the subnet mask 255.255.255.192<\/code>. The number of available host IP addresses is calculated as:<\/p>\n\n\n\n
[ 2^6 – 2 = 62 \\text{ IP addresses} ]<\/p>\n\n\n\n
The subtraction of 2 accounts for the network address and the broadcast address, which cannot be assigned to hosts.<\/p>\n\n\n\n
\n\n\n\n
300-Word Explanation<\/h3>\n\n\n\n
A subnet mask<\/strong> helps divide an IP address into the network portion and the host portion. In this case, the subnet mask 255.255.255.192<\/code> divides the address into 26 bits for the network and 6 bits for the host. The first 26 bits (11111111.11111111.11111111.11000000<\/code>) are fixed for the network, while the remaining 6 bits (000000<\/code>) are for the host addresses.<\/p>\n\n\n\n
Borrowing bits<\/strong> from the host portion increases the number of subnets by reducing the number of available IPs for hosts. By borrowing 2 bits (from the 6 bits reserved for hosts), we increase the number of subnets by 2^2 = 4<\/code>. This means that, with this subnet mask, we can create 4 subnets in total.<\/p>\n\n\n\n
Each of these subnets can support up to 62 host addresses. The formula 2^n - 2<\/code> (where n<\/code> is the number of host bits) gives the number of usable host addresses in a subnet. The two subtracted addresses are reserved for the network address<\/strong> (which identifies the subnet itself) and the broadcast address<\/strong> (which is used to communicate with all devices on the subnet).<\/p>\n\n\n\n
In conclusion, the subnet mask 255.255.255.192<\/code> creates 4 subnets, each with 62 usable IP addresses for hosts. The network and broadcast addresses for each subnet cannot be used for devices.<\/p>\n\n\n\n\n\n\n\n
