Let&#8217;s break down each option and why it matches (or does not) the given descriptions.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">1. <strong>Private address:<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Private IP addresses are reserved for use within private networks and are not routable on the public internet. The common private IP address ranges are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>10.0.0.0 to 10.255.255.255<\/li>\n\n\n\n<li>172.16.0.0 to 172.31.255.255<\/li>\n\n\n\n<li>192.168.0.0 to 192.168.255.255<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The address <strong>172.10.20.5<\/strong> falls within the 172.0.0.0 to 172.15.255.255 range, which is <em>not<\/em> private. The private range is specifically 172.16.0.0 to 172.31.255.255. Therefore, 172.10.20.5 is <strong>not<\/strong> private. So this option is a bit tricky: it&#8217;s <em>close<\/em> but outside the private range.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Reconsidering, the private addresses among these options are actually none, because 172.10.20.5 is outside the private range.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let&#8217;s reanalyze the given options with accurate ranges:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>169.254.1.5<\/strong> is in the range 169.254.0.0\/16, which is <strong>link-local<\/strong>.<\/li>\n\n\n\n<li><strong>192.0.2.123<\/strong> is in the 192.0.2.0\/24 block reserved for <strong>TEST-NET<\/strong> (documentation and examples).<\/li>\n\n\n\n<li><strong>240.2.6.255<\/strong> falls within 240.0.0.0\/4, which is reserved for <strong>experimental<\/strong> or future use.<\/li>\n\n\n\n<li><strong>64.102.90.23<\/strong> is a regular public IP, not private, link-local, experimental, or loopback.<\/li>\n\n\n\n<li>Loopback addresses are in the range 127.0.0.0\/8 (e.g., 127.0.0.1), none provided here.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Private addresses from the options? None exactly fit the private ranges. So none of the addresses provided qualify as private.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Corrected Matching:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a private address:<\/strong> <em>None provided<\/em> (172.10.20.5 is outside the private range)<\/li>\n\n\n\n<li><strong>a loopback address:<\/strong> <em>None provided<\/em><\/li>\n\n\n\n<li><strong>an experimental address:<\/strong> 240.2.6.255<\/li>\n\n\n\n<li><strong>a TEST-NET address:<\/strong> 192.0.2.123<\/li>\n\n\n\n<li><strong>a link-local address:<\/strong> 169.254.1.5<\/li>\n\n\n\n<li><strong>64.102.90.23:<\/strong> <em>Public address, none of the above<\/em><\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Detailed explanation of these special IP address categories:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Private addresses<\/strong> are used for internal networks and cannot be routed on the public internet to protect network security and reduce global IP address consumption. The three ranges are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>10.0.0.0\/8<\/li>\n\n\n\n<li>172.16.0.0\/12<\/li>\n\n\n\n<li>192.168.0.0\/16<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Since 172.10.20.5 is outside the 172.16.0.0 to 172.31.255.255 range, it is not private.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Loopback addresses<\/strong> are used by a device to communicate with itself. These addresses are in the 127.0.0.0\/8 range, most commonly 127.0.0.1.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Experimental addresses<\/strong> are in the range 240.0.0.0 to 255.255.255.254 (excluding 255.255.255.255). These are reserved for future use and generally not assigned publicly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>TEST-NET addresses<\/strong> (192.0.2.0\/24, 198.51.100.0\/24, 203.0.113.0\/24) are reserved for documentation and examples. They never appear on the public internet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Link-local addresses<\/strong> (169.254.0.0\/16) are automatically assigned when DHCP fails, allowing devices on the same network segment to communicate without a DHCP server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Public addresses<\/strong> like 64.102.90.23 are routable on the internet and don&#8217;t fall into any special reserved category.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Summary table:<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Description<\/th><th>IP Address<\/th><th>Reason<\/th><\/tr><\/thead><tbody><tr><td>Private address<\/td><td><em>None<\/em><\/td><td>172.10.20.5 is not in private range<\/td><\/tr><tr><td>Loopback address<\/td><td><em>None<\/em><\/td><td>No 127.x.x.x address provided<\/td><\/tr><tr><td>Experimental address<\/td><td>240.2.6.255<\/td><td>Falls in 240.0.0.0\/4 reserved range<\/td><\/tr><tr><td>TEST-NET address<\/td><td>192.0.2.123<\/td><td>Reserved for documentation\/examples (TEST-NET)<\/td><\/tr><tr><td>Link-local address<\/td><td>169.254.1.5<\/td><td>In 169.254.0.0\/16 link-local range<\/td><\/tr><tr><td>Public (no category)<\/td><td>64.102.90.23<\/td><td>Regular public IP, no special categor<\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Match each description with an appropriate IP address.
