Which of the following is a private address (RFC1918)?

All the provided addresses fall within the ranges specified by RFC 1918 for private IP addresses. According to RFC 1918, the following three ranges are designated for private use:

1. 10.0.0.0 to 10.255.255.255

2. 172.16.0.0 to 172.31.255.255

3. 192.168.0.0 to 192.168.255.255

• The address 172.16.254.1 is within the 172.16.0.0 to 172.31.255.255 range, making it a private address.

• The address 10.45.60.10 falls within the 10.0.0.0 to 10.255.255.255 range, confirming its status as a private IP address.

• The address 192.168.1.1 is part of the 192.168.0.0 to 192.168.255.255 segment, classifying it as a private address as well.

Since all three addresses are part of the specified private ranges, the correct answer includes all of them. This understanding of private versus public IP addresses is
