title: Assigning IP block to CentOS with different netmask & gateway
body: <p>Trying to assign an IP block in CentOS 6.4:</p>
  <blockquote>
  <p>IP Range: 23.252.117.2 to 23.252.117.14</p>
  <p>Netmask: 255.255.255.240</p>
  <p>Gateway: 23.252.117.1</p>
  </blockquote>
  <p>I've tried doing it through ifcfg-eth0-range0:</p>
  <blockquote>
  <p>IPADDR_START=23.252.117.2</p>
  <p>IPADDR_END=23.252.117.14</p>
  <p>CLONENUM_START=10</p>
  <p>NETMASK=255.255.255.240</p>
  <p>BROADCAST=23.252.117.15</p>
  <p>GATEWAY=23.252.117.1</p>
  </blockquote>
  <p>When I use</p>
  <blockquote>
  <p>ifup ifcfg-eth0-range0</p>
  </blockquote>
  <p>It returns</p>
  <blockquote>
  <p>Device does not seem to be present, delaying initialization.</p>
  </blockquote>
  <p>Network restart appears to assign the IPs however they do not work properly (I use them for Minecraft servers and they can't be connected to through IPs in ifcfg-eth0-range0)</p>
  <p>Any ideas?</p>
