- Where is eduroam Wi-Fi available?
- What is my IP Address?
Upon successful authentication, your IP address is automatically allocated using DHCP.
For Internal users (@ucl.ac.uk), a Private IP address from 10.111.0.0/16 is allocated. When accessing resources (e.g. Internet, Email) your address will be translated to one of the following:
- 22.214.171.124/22 (126.96.36.199 - 188.8.131.52)
- 184.108.40.206/19 (220.127.116.11 - 18.104.22.168)
- 22.214.171.124/19 (126.96.36.199 – 188.8.131.52)
- 184.108.40.206/20 (220.127.116.11 – 18.104.22.168)
- 22.214.171.124/21 (126.96.36.199 - 188.8.131.52)
Traffic on this subnet is presented Inside the Institutional Firewall (IFW).
For External users (not @ucl.ac.uk), an IP address from the 184.108.40.206/22 (220.127.116.11 - 18.104.22.168) subnet is allocated. Traffic on this subnet is presented Outside the Institutional Firewall (IFW).
To determine your actual IP address you can either check your adapter configuration or type "My IP Address" in your web browser search engine.
- How do I connect to eduroam at other institutions?
You use the same connection instructions and UCL userid and password at other Institutions as you do here at UCL. We (UCL) are currently at JRS Tier-2 - this allows the Institution to support either WPA/TKIP or WPA2/AES encryption (or both) - UCL supports both. Support at other Institutions may differ. It is therefore recommended you (a) check eduroam works here at UCL and (b) check the JRS eduroam web site for details on the status of eduroam at participating Institutions.
- What is eduroam?
eduroam is a JANET Roaming Service (JRS) that provides an infrastructure for a user to use their UCL credentials (e.g. firstname.lastname@example.org) to access the Internet from UCL or any participating Institution. The instructions for connecting are the same regardless of location. However, it is recommended you (a) check eduroam works here at UCL and (b) check the JRS eduroam web site for details on the status of eduroam at participating institutions.
- How do I connect to eduroam?
eduroam is supported on any Wi-Fi enabled device. View our connection guides for instructions on how to set eduroam up on your device.
