Static IP address is an IP address which needs to be configured manually on the Server, network printer or devices. The IP address will not be changed after power-off or reboot.

A public IP address is accessible freely by anyone and from anywhere over the Internet. A private IP address requires the user to be connected to NUS’ network (either via WiFi, ethernet or NUS VPN if outside campus) before accessing.

Most of the time dynamic IP address will be sufficient. You will need Static IP address in below scenarios.

• Need to host dedicated services (web, email, FTP, VPN, printing, video, audio etc.)

• Need to support name resolution (web, FTP, backup etc.)

• Device does not support DHCP

• Program that you want to access require static IP

• Remote access/administration to system

Private IP
You run one or more services on your system that ONLY require campus access (within NUS).

 

• Department server (Application, Database, middleware)

• Printer/Copier/Scanner

• IP camera/CCTV/surveillance device

• Network storage

• Network devices

• Instrument/sensor

• Client machine for specific application

• Audio/Video equipment

Public IP
You run one or more services on your system that require external access (from the Internet).

• Web server

• Video conferencing device

• Email server/Email gateway

• VPN devices

No, you do not need static IP addresses for that.

Only NUS staff and contractors with a valid NUS-ID are eligible to apply for static IP address.

Yes, if your department has been allocated a specific IP subnet.

You can keep the IP address as long you have a requirement to use it. If you no longer require the IP address, do inform IT Care to remove it.

Always keep IT Care updated on any changes to your IP address, such as ownership, contact information. Location, network point information, etc. You are responsible for securing the static IP devices too, apply security patches and fixing all security vulnerabilities timely.

Security vulnerabilities scans for systems/devices with static IP addresses are a part of a holistic network security framework to keep NUS data and systems safe. As an owner of a static IP address, you are also responsible for resolving any vulnerability reported for static IP address under your care.
