When calculating subnets and subnet masks, there are special numbers that reoccur and remembering these numbers is essential. For example, if the value of each channel is set to 255, the color of the visualized color space results in white. * */ color : white color : black color : red color : green color : blue color : cyan color : rebeccapurple /* (#rrggbb | #rgb | #rrggbbaa | #rgba)*/ color : #ffffff color : #000000 color : #ff0000 color : #00 ff00 color : #0000 ff color : #00 ffff color : #663399 color : #639 color : #66339977 color : #6397 /* (rgb(), rgba()) */ color : rgb ( 255, 255, 255 ) color : rgb ( 0, 0, 0 ) color : rgb ( 255, 0, 0 ) color : rgb ( 0, 255, 0 ) color : rgb ( 0, 0, 255 ) color : rgb ( 0, 255, 255 ) color : rgb ( 102, 51, 153 ) color : rgba ( 102, 51, 153, 0. R red (0 R 255) G green (0 G 255) B blue (0 B 255) In the RGB color space, the light intensity of each channel is equal to the value of each channel. Use 255.255.255.0 for the subnet mask Use 192.168.0.5 for the default gateway Use 163.128.78.93 or 163.128.80.93 as the preferred DNS server In Configure settings for Local Area Connection 2 Hide Details Use 10.0.255.254 for the IP address Use 255.255.0.0 for the subnet mask Do not configure a default gateway address Do not configure a DNS.
