cursor: text;\">Yeah, that&#8217;s usually the basic information a device such as a computer or IP camera needs to become a part of the network and navigate the Internet.<\/p>\n<p style=\"text-align: justify; cursor: text;\">But the DHCP server can give much more information to the devices.<\/p>\n<p style=\"text-align: justify; cursor: text;\">It&#8217;s possible to use options for Hostname, NTP Server, and much more&#8230;<\/p>\n<p style=\"text-align: justify; cursor: text;\">These options are configured in the DHCP server and are represented by numbers.<\/p>\n<p style=\"text-align: justify; cursor: text;\">Here are some examples:<\/p>\n<ul>\n<li style=\"text-align: justify; cursor: text;\">Option 3: Gateway address to be assigned to the clients.<\/li>\n<li style=\"text-align: justify; cursor: text;\">Option 6: DNS server IP address to be assigned to the clients.<\/li>\n<li style=\"text-align: justify; cursor: text;\">Option 12: The hostname assigned to the clients.<\/li>\n<li style=\"text-align: justify; cursor: text;\">Option 33: Classful static routes a client should add into its routing table<\/li>\n<li style=\"text-align: justify; cursor: text;\">Option 51: The IP address lease.<\/li>\n<li style=\"text-align: justify; cursor: text;\">Option 53: Identifies the type of the DHCP message.<\/li>\n<li style=\"text-align: justify; cursor: text;\">Option 55: &nbsp;DHCP client request specified configuration parameters.<\/li>\n<li style=\"text-align: justify; cursor: text;\">Option 60: DHCP client to identify its vendor.<\/li>\n<li style=\"text-align: justify; cursor: text;\">Option 66: The TFTP server domain name to be assigned to the clients.<\/li>\n<\/ul>\n<h3 style=\"text-align: justify; cursor: text;\">DHCP server option 12 configuration<\/h3>\n<p style=\"text-align: justify; cursor: text;\">The configuration varies according to the DHCP server you have available.<\/p>\n<p style=\"text-align: justify; cursor: text;\">You can use a Cisco router or software running on Linux or Windows.&nbsp;<\/p>\n<p style=\"text-align: justify; cursor: text;\">I&#8217;m using the Open DHCP Server running on Windows for the tests.&nbsp;<\/p>\n<p style=\"text-align: justify; cursor: text;\">I can specify which IP and hostname the camera gets via its MAC Address.<\/p>\n<p style=\"text-align: justify; cursor: text;\">Here&#8217;s an example of the server configuration.<\/p>\n<p style=\"text-align: justify; cursor: text;\">[AC:CC:8E:9B:A3:EE]<\/p>\n<p style=\"text-align: justify; cursor: text;\">IP=192.168.0.212<\/p>\n<p style=\"text-align: justify; cursor: text;\">HostName=P3225_MKII<\/p>\n<p style=\"text-align: justify; cursor: text;\">This is the extra configuration that is done beyond the standard one.<\/p>\n<p style=\"text-align: justify; cursor: text;\">It&#8217;s meant to tell the DHCP server to always give the camera with a specific MAC Address the same IP address and hostname.<\/p>\n<h3 style=\"text-align: justify; cursor: text;\">DHCP server option 12 test<\/h3>\n<p style=\"text-align: justify; cursor: text;\">After configuring the server with the hostname option, you can run a test.<\/p>\n<p style=\"text-align: justify; cursor: text;\">Just connect the camera to the same network as the DHCP server and observe the logs showing the IP and hostname allocation for that device.<\/p>\n<p style=\"text-align: justify; cursor: text;\">The following picture shows the hostname P3225_MKII allocated to the camera.<\/p>\n<p><span><img decoding=\"async\" alt=\"DHCP Server Gives camera IP-correctly\" data-id=\"27734\" width=\"719\" data-init-width=\"784\" height=\"135\" data-init-height=\"147\" title=\"DHCP Server Gives camera IP-correctly\" loading=\"lazy\" src=\"https:\/\/learncctv.com\/wp-content\/uploads\/2021\/11\/DHCP-Server-Gives-camera-IP-correctly.jpg\" data-width=\"719\" data-height=\"135\"><\/span><\/p>\n<p style=\"text-align: justify;

cursor: text;\">And then you have your camera with the IP and hostname set.<\/p>\n<p style=\"text-align: justify; cursor: text;\">But remember that the camera must have the correct configuration to negotiate the hostname and display it as well (as seen in the first picture in this article).<\/p>\n<p style=\"text-align: justify; cursor: text;\">Let&#8217;s take a look at how to set up the camera.<\/p>\n<h2 style=\"text-align: justify; cursor: text;\">How to set up the &nbsp;camera to get a hostname<\/h2>\n<p style=\"text-align: justify; cursor: text;\">Yeah, I&#8217;m using an Axis camera in this example.<\/p>\n<p style=\"text-align: justify; cursor: text;\">The concept is similar for other make\/models, but that option may be available or not according to the device you are using. Here, let&#8217;s see how it work on Axis.<\/p>\n<h3 style=\"text-align: justify; cursor: text;\">Enable the Network Volatile HostName<\/h3>\n<p style=\"text-align: justify; cursor: text;\">You must enable the &#8220;<em><strong>Obtain from DHCP<\/strong><\/em>&#8221; option in the camera.<\/p>\n<p><span><img decoding=\"async\" alt=\"P3225 MKII Enable DHCP\" data-id=\"27731\" width=\"666\" data-init-width=\"666\" height=\"63\" data-init-height=\"63\" title=\"P3225 MKII Enable DHCP\" loading=\"lazy\" src=\"https:\/\/learncctv.com\/wp-content\/uploads\/2021\/11\/P3225-MKII-Enable-DHCP.jpg\" data-width=\"666\" data-height=\"63\"><\/span><\/p>\n<p style=\"text-align: justify; cursor: text;\">This option is under the &#8220;<em>plain config<\/em>&#8221; &nbsp;menu in an Axis camera.<\/p>\n<p style=\"text-align: justify; cursor: text;\">The location varies according to the model. Here&#8217;s an example of how you can find this option for two different cameras that use an old and new menu.<\/p>\n<p style=\"text-align: justify; cursor: text;\">For the Old menu (e.g. P3225-V MK II camera)<\/p>\n<p style=\"text-align: justify; cursor: text;\">Go to: <strong>Setup <\/strong>&gt; <strong>System <\/strong><strong>Option <\/strong>&gt; <strong>Advanced <\/strong>&gt; <strong>Plain Config &gt; Network<\/strong>.<\/p>\n<p style=\"text-align: justify;

Network<\/strong>.<\/p>\n<p style=\"text-align: justify; cursor: text;\">For both cases, you need to look for the Network Options and ensure the option &#8220;Obtain from DHCP&#8221; is checked (as seen in the previous picture).<\/p>\n<p style=\"text-align: justify; cursor: text;\">After checking the box, the camera is ready to get the hostname from the server.<\/p>\n<p style=\"text-align: justify; cursor: text;\">Now you need to check if everything is working on the camera side.<\/p>\n<h3 style=\"text-align: justify;
