Which of the following is a private IP network address reserved by the IANA?
Which of the following is a private IP network address reserved by the IANA?
The IANA (Internet Assigned Numbers Authority) has reserved specific IP addresses for private networks. The private IP address ranges include, among others, the 172.16.0.0 to 172.31.255.255 range, which falls under the 172.16.0.0/12 block. Option 172.30.0.0/16 falls within this range, making it a valid private address.
To determine which of the given IP addresses is a valid host address within the subnet, we need to consider the subnet mask: 172.16.224.255/18 - MASK: 11111111.11111111.11|000000.00000000 - To determine if an IP address is a valid host address, we need to check if the host portion (the last 14 bits) is all zero or all ones. - HOST: 10101100.0001 0000.11|000000.11111111 - That's a valid host. 255.255.255.255/32 - That's a Broadcast. 224.1.2.1/8 - That range is reserved for multicast address. 192.168.24.59/30 - MASK: 11111111.11111111.11111111.111111|00 - To determine if an IP address is a valid host address, we need to check if the host portion (the last 2 bits) is all zero or all ones. - HOST: 1100 0000.10101000.00011000.001110|11 - That's a Broadcast. So, the correct answer is A.
169.254.0.0/16 is a reserved private address for automatic private addressing
In the course's reference the 169.254.0.0/16 is the right answer
though, 172.30.0.0/16 is not an accurate answer, but still is a valid one because it is derived from the 172.16.0.0/12 private address
