IP Address Management

Every device that connects to the internet—laptops, cellphones, servers, gaming consoles—has a unique Internet Protocol (IP) address that identifies the device. Think of it as the phonebook of the internet. At FSU, ITS uses DHCP (Dynamic Host Configuration Protocol) to assign IP addresses. These IP addresses are assigned automatically from a defined range of numbers whenever a device connects to an FSU wired or wireless network. University departments may request an expanded range of numbers for IP addresses or static IP addresses that remain constant for particular devices. 

  • Automatic | unique IP addresses automatically assigned to devices
  • Unique identifier | pinpoints your computer on the network
  • Portable | devices can roam around campus without having to reconfigure IP settings
  • Wired and wireless connections | assigned to all wired and mobile devices, including printers, laptops and cellphones
  • Static address | departments can request IP address that remains the same every time device connects to network

Additional Info

ITS implements:

  • The Management of campus IP infrastructure
  • Prevents subnets and DHCP scopes from filling up
  • Periodically audits the network and DHCP servers for IP changes
  • IPv4 addresses assigned to FSU and Private IPv4 addresses managed by ITS (use of Private IPv4 address on campus requires allocation from ITS to avoid duplication)
    • 128.186.xxx.xxx, 146.201.xxx.xxx
    • Private IPv4 address space (aka RFC1918):
