Campuswide DHCP

General Information

According to Wikipedia, the "Dynamic Host Configuration Protocol (DHCP) automates the assignment of IP addresses, subnet masks, cleared for copywritdefault gateway, and other IP parameters".  This allows the administrators of a large network, such as LSU, to quickly and centrally make changes to the IP network.  With an impending network redesign in store, the Networking & Infrastructure (NI) department of Information Technology Services has decided to move toward a campus-wide DHCP standard.

What does this mean?  All machines on campus will be configured via DHCP.  The servers, printers, etc. that need static addresses will still be configured via DHCP, but will have a static reservation that ensures the issuance of the same IP for every renewal.  Exceptions to this rule are allowed for devices with no DHCP client available and will be handled case by case.

Registration for static DHCP reservations is very similar to registration for dynamic DHCP via Netreg.  Administrators belonging to the LSU Network Contacts Active Directory group will be allowed to log into an application (http://ipcontrol.lsu.edu) to register devices.  If you do not have an administrative group for your department, please create a NI Service Request indicating your need to have one created.  The departments that already have a group created should check the integrity of the membership.  Please keep in mind that students will not be able to access this application even if they are a member of the Network Contacts group.

Hints and Tips

Note: To check the current IP settings, see the following category:  Getting your IP Address.

• Static reservations do NOT count against your limit for dynamic registrations processed through NetReg.
   
• You will be issued the same IP you currently have IF you register using the same hostname prior to the network redesign.
   
• You will essentially be in control of your names and equally responsible for those names.
   
• How do I reserve a static IP through DHCP via the IPControl application?
   
• How do I get added to the TSP group?
  • ??Send a request to helpdesk@lsu.edu.
• When do I have to have my devices moved to DHCP?
  • The absolute deadline is the day your subnet is readdressed.
• What if I have multiple IPs for one machine?
  • Please see the bottom of the GROK article linked above.
  • As of now, multiple IPs need direct attention.
