The reasons for this can be any of dozens, but thankfully the fix is always the same, namely resetting your IP address.<\/p>\n<p>To do so, you first need to know your current IP address. You can do so using the following command:<\/p>\n<pre>ip address<\/pre>\n<p>Alternatively, some Linux distros will allow you to do this within the desktop environment, check out our article on\u00a0<a href=\"https:\/\/www.howtogeek.com\/17012\/how-to-find-your-ip-address-in-ubuntu\/\" target=\"_blank\" rel=\"noopener\">how to find your IP address in Ubuntu<\/a>.<\/p>\n<p>Though it\u2019s not necessary, you may want to take note of this IP address as after we\u2019re done we need to check that it\u2019s been changed.<\/p>\n<p>Next, we need to request a new IP address through your DHCP server. We have a full explainer on\u00a0<a href=\"https:\/\/www.howtogeek.com\/404891\/what-is-dhcp-dynamic-host-configuration-protocol\/\" target=\"_blank\" rel=\"noopener\">what DHCP is<\/a>, but the short version is that it\u2019s a protocol that handles IP assignments. It usually does this on a daily basis, so your network gets a new IP every 24 hours. What we\u2019re going to do is ask if we can renew it now.<\/p>\n<p>To do so you need a program called dhclient, which is installed by default on Linux systems. Run it to find out what your system is running now, using the \u201cverbose\u201d command (-v) to make sure you get some output:<\/p>\n<pre>sudo dhclient -v<\/pre>\n<div class=\"body-img landscape \">\n<div class=\"responsive-img image-expandable img-article-item\" data-img-url=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png\" data-modal-id=\"single-image-modal\" data-modal-container-id=\"single-image-modal-container\" data-img-caption=\"&quot;&quot;\">\n<figure><picture><source srcset=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png?q=70&amp;fit=crop&amp;w=825&amp;dpr=1\" media=\"(min-width: 1024px)\" data-srcset=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png?q=70&amp;fit=crop&amp;w=825&amp;dpr=1\" \/><source srcset=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png?q=70&amp;fit=crop&amp;w=825&amp;dpr=1\" media=\"(min-width: 768px)\" data-srcset=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png?q=70&amp;fit=crop&amp;w=825&amp;dpr=1\" \/><source srcset=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png?q=70&amp;fit=crop&amp;w=800&amp;dpr=1\" media=\"(min-width: 481px)\" data-srcset=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png?q=70&amp;fit=crop&amp;w=800&amp;dpr=1\" \/><source srcset=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png?q=70&amp;fit=crop&amp;w=500&amp;dpr=1\" media=\"(min-width: 0px)\" data-srcset=\"https:\/\/static1.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2024\/09\/dhclient-verbose-output.png?q=70&amp;fit=crop&amp;w=500&amp;dpr=1\" \/><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/sudlatnid.com\/wp-content\/uploads\/2024\/10\/dhclient-verbose-output.png\" alt=\"Verbose output from dhclient.\" width=\"654\" height=\"309\" data-img-url=\"http:\/\/sudlatnid.com\/wp-content\/uploads\/2024\/10\/dhclient-verbose-output.png\" \/><\/picture><\/figure>\n<\/div>\n<\/div>\n<p>This lets you know what IP was requested (DHCPREQUEST) and when it will expire, in my case 40157 seconds from now, which is about 11 hours.<\/p>\n<p>Now, we need to release the IP address, which means we ask dhclient to trash it.
