In addition to self-operated websites and email services, we also provide free services for a very limited group of users.<\/p>\n\n\n\n<p>Leveraging past experience in server construction and operation at IT companies, we have made efforts to make the servers more professional, more convenient, and more enjoyable to use.<\/p>\n\n\n\n<p>Although it has not gone beyond the level of personal satisfaction, we would be honored if home server enthusiasts who visit this page could find even a little reference useful.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">The structure of the sky-nest network<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"683\" height=\"1024\" src=\"https:\/\/www.sky-nest.jp\/wp-content\/uploads\/2026\/06\/file_00000000556c7209906f82e2ad6fd385-683x1024.png\" alt=\"\" class=\"wp-image-72\" srcset=\"https:\/\/www.sky-nest.jp\/wp-content\/uploads\/2026\/06\/file_00000000556c7209906f82e2ad6fd385-683x1024.png 683w, https:\/\/www.sky-nest.jp\/wp-content\/uploads\/2026\/06\/file_00000000556c7209906f82e2ad6fd385-200x300.png 200w, https:\/\/www.sky-nest.jp\/wp-content\/uploads\/2026\/06\/file_00000000556c7209906f82e2ad6fd385-768x1152.png 768w, https:\/\/www.sky-nest.jp\/wp-content\/uploads\/2026\/06\/file_00000000556c7209906f82e2ad6fd385.png 1024w\" sizes=\"auto, (max-width: 683px) 100vw, 683px\" \/><\/figure>\n\n\n\n<p>The network that constitutes sky-nest connects one host server and ten guest servers, and by isolating LANs according to usage (VLAN), it achieves both security and ease of use.<\/p>\n\n\n\n<p>Additionally, many of the host servers and various terminals are modified PCs that were used as Windows machines for 15 years in the past. We think that by doing this, we are also contributing, even slightly, to resource conservation such as reducing waste.<\/p>\n\n\n\n<p>Also, with the slogan &#8220;Where Birds Work Together,&#8221; the host server is named &#8216;sky,&#8217; and each server uses the name of a bird. By making each server as single-purpose as possible, it is easy to understand and maintain, which is another feature.<\/p>\n\n\n\n<p>Example:<br>kamome \u2192 Web server (a bird that delivers information across the sea)<br>hato \u2192 Mail server (a carrier pigeon that delivers mail), etc.<\/p>\n\n\n\n<p class=\"has-medium-font-size\">sky-nest Server Technical Information (For
