I'm facing a challenge with two labs that need me to clean up their environments. The IP addresses are assigned based on server locations, like Server1 in rack R44, U position 22, which gives an IP such as 10.0.244.22. Breaking it down, the x.x.244 part shows the rack, and the x.x.x.22 indicates the U position. The naming convention combines the model number with rack and U position—for instance, DL360gen10r44u22. This setup helps quickly identify a server by IP or name. However, since servers are frequently moved, relying on IPs or names becomes unreliable. If one server's IP changes, others may point to incorrect locations. You're wondering how to maintain consistency when servers shift. One possible solution is setting up a DNS lookup using nslookup. This would let you search for the server name from an IP address, helping you track its location without needing to restart the system or change BMC/eth addresses. The local admin would just update the name after moving the server, which avoids disrupting the network configuration. Any suggestions would be greatly appreciated.
It doesn’t make much sense to relocate a server. I understand you’re not the one handling the moves, but still. Could renaming them by role—like PDC, BDC, SQL Server—help? Or better yet, include the function in the "computer description" section under the Identifier and add a Dymo label for clarity. Just a suggestion.
I believe the main reason systems shift frequently is that remote teams use them to evaluate and compare hardware, constantly changing configurations. I think moving them from an internal to external network explains much of the activity, though there are more efficient approaches. Regarding documentation, static jobs or clear purposes aren't really needed, making descriptions less valuable.
If Linux can consistently update server hostnames to reflect rack locations and U numbers, a cron job could automate this process—running a script every hour (or sooner)—to adjust the IP address based on the new hostname.
