1. Write the IP address 222.1.1.20 mask 255.255.255.192 in CIDR notation. Recall that CIDR notation uses the IP address in dotted decimal followed a /n, where n is the number of significant or "unmasked" bits 2. A network administrator wants to place 27 subnets on a /23 network.  How many bits would be in the host field of the address? Just enter the integer number of bits with no label.

Don't copy answer from previous answers Suppose an ISP has the following IP address block: 130.12.128.0/23. Assume that the ISP wants to divide its address block (130.12.128.0/23) into two equal-sized contiguous address blocks, and give one of these address blocks to its customers (C1 and C2). Provide network addresses (of the form a.b.c.d/x) for C1 and C2. Now let’s assume that the ISP wants to divide its address block (130.12.128.0/23) into four equal-sized contiguous address blocks, and give one of...
