To request a static IP address for a printer or other device, send an email to the uiowa hostmaster at firstname.lastname@example.org.
The email should include:
- Customer name (including both the person requesting the static IP address and the person responsible for the device)
- Room number
- Hostname information (what the device is to be called - this usually is worked out between the requesting party and hostmaster)
- Data jack information (jack and port number)
- MAC address for the device (if applicable)
- What type of static IP address (local-scope or global)
- A brief description of the need for a static IP address (software requirements, shared network devices such as printers, servers, special hardware, etc.)
If requesting local-scope addressing (LSA), the network port associated with the jack must be configured for the local-scope network. Hostmaster will automatically switch the jack/port to LSA as part of the LSA IP request. Therefore, it is very important that the data jack information is accurate. Wired network jacks on the University network have a numeric jack number and port number. 12546-3, for example, would be port 3 on network jack 12546. On network jacks with more than one port, the port number is determined as follows:
port 1 is top left
port 2 is top right
port 3 is bottom left
port 4 is bottom right
Please note: Although a local-scope address is assigned to a specific device, the jack/port that the device is using must be configured for the local-scope network. If you need to move a device that has a local-scope address (172.30.x.x), you will need to coordinate with hostmaster to ensure the new jack is configured for the local-scope network. Most jacks on campus are currently on the global network (128.255.x.x). Local-scope addressing is being used more frequently for devices such as printers that do not need to talk off the campus network. This not only saves our IPv4 global addresses for devices that do need to talk off campus, but provides a limited scope of reachability (campus and remote-VPN) for devices such as printers that do not need to be on the global network.
Note: Due to the architecture of the wireless service, we do not support assigning global static IP addresses to wireless clients at this time.
