Departmental DHCP

Dynamic Host Configuration Protocol (DHCP) provides IP addresses to computers on many parts of campus and in the residence halls.

DHCP allows administrators to manage network host assignments from a single DHCP server. This method helps reduce the work required when managing a large network.

Texas A&M IT offers a university wide DHCP service that can be viewed through the Infoblox interface. Texas A&M IT recommends all departments move to this service, however departments are allowed to manage their own DHCP. If you choose to manage your own DHCP server, please follow the steps below.

Getting Started

To run a DHCP server, a departmental administrator must meet the requirements below:
  1. Initial set up and configuration of the DHCP server must be coordinated with the Networking and Information Security teams. Send mail to consult@tamu.edu to begin this process.
  2. IP addresses used in the department's DHCP address space must be claimed in infoblox.
  3. DHCP logs of IP address/MAC address mapping and IP address users MUST be maintained for 30 days. Texas A&M IT can provide this service if needed.
  4. Anonymous access to the campus network is not allowed. This includes wireless access. For more information on anonymous access, read the User Authentication Guidelines.

Help and Support

IP addresses and mappings to domain names for most Texas A&M machines are assigned and maintained using Infoblox. Many domain names are placed in the tamu.edu root domain. However, subdomains and .org domains can be registered.

Note for administrators with network-based access lists:  The following IP address space is used on campus. To ensure that all campus users can access your service, please include the following address space in your access lists.

  • Primary campus address space: 128.194.0.0/16 and 165.91.0.0/16
  • Campus VPN address space: 128.194.199.0/24, 165.91.48.0/23 and 172.16.48.0/23
  • Campus private address space: 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16
