Campus IP Space

Heads up! For the most up to date information and resources, visit the IT Help Portal to browse a full list of services and instructions.

Each building network provides a Class A IPv4 subnet and an IPv6 subnet.

IPv4 addresses are private and not accessible directly from the internet. Network address translation (NAT) is used to pass traffic to the internet. All private addresses can be directly accessed on campus.

Devices are automatically assigned a temporary address through DHCP, starting at the top end of each IP range. Static IP addresses are assigned at the bottom of the range. For example:

Subnet mask

Dynamic range to
Static range to

Public IP Space

The University of Arkansas has been allocated public IP space in the range of

Building networks are being converted to use private IP space, bringing increased security, hostname-based dynamic DNS and increased subnet capacity. Public IP addresses are assigned on a case-by-case basis only.

NAT (Network Address Translation)

Private IPs NAT at the campus central firewall to internet hosts only.

Private networks route to all campus IP space, including directly.

An external IP will appear as an address in the subnet.

Most applications will operate in a NAT environment.

Static Private IP Guidelines

Static IP address are allocated in address blocks outside of the DHCP ranges above.

Users can request static IP addresses by creating a ticket.

Approved campus IT can use the Infoblox Grid tool at to register static IP devices or schedule changes. The network team must approve changes and additions. VPN is required when connecting to Infoblox, even when on campus.
