Hey all, I suppose this isn't exactly a noob question... When I add a /24 for example to a CentOS server I edit the ipcfg-ethX file and add (depending on the range) IPADDR_START=192.168.1.0 IPADDR_END=192.168.1.255 And then restart the network. Sometimes this can take 10+ minutes. I know other systems that can add a /16 faster than that. I'm upping my game to larger IP ranges and am wondering what tricks or tools are used to add/bind IPs faster with bigger ranges. I've been googling this for an hour or so but haven't found any shortcuts - apparently not that many people add large blocks to servers. /24s are common. But if I were to add a /22 or /18 or bigger, this could take forever. I know there are easier ways, I just haven't found them yet. Thanks for any input or help. I'm not a skilled admin so a tool or tutorial would be appreciated.
