The SLAC Visitor Network
Last updated: November 2019

The visitor network is a SLAC operated network (a subnet of SLAC managed IP addresses) which is outside the SLAC enterprise network firewall. Systems connected to it are effectively treated as if they were on any commercial or public ISP and will be assigned, via DHCP, a 198.129.n.n IP address. Because it is outside the firewall connections should be considered to be very insecure. It is the responsibility of users of the Visitor network to protect their communications, e.g. by using a Virtual Private Network (VPN).

The visitor network is meant for light casual use and to provide an easy network connection for SLAC visitors, collaborators, conference/meeting attendees, vendor demonstration etc. Do not place mission applications on the Visitor network.

Access the visitor network

• Connect by using Ethernet a wireless laptop connection. 

• The visitor network is available in SLAC conference and meeting rooms and in areas supporting wireless networking.

• Set your laptop network configuration for DHCP. A DHCP server will provide your laptop with the necessary network information e.g. IP address, gateway address, and DNS server addresses.

• To connect for the first time you will need to open a web browser and attempt to connect to any normal internet web site (we suggest http://www.slac.stanford.edu). If your browser was already running, you may have to hit the "refresh" button. 

• You will be redirected to a portal web page that provides basic information about the SLAC Visitor Network and asks you to provide some information about yourself. The purpose of asking you for this information is so that you can be contacted in the event that your computer has a security issue or causes problems with the network. Re-registration is required after 90 days. Before you can proceed to the network, you will need to agree to the SLAC Acceptable Use Agreement regarding network use. After you agree, your system will be given network access.

SLAC Specific Services

• To access resources made available only to the SLAC interior network(134.79.nn.nn), use VPN, SSH, Citrix.

• To print from the Visitor's subnet see Printing at SLAC

Service and support

• Support for the visitor network is on a best effort basis. If a problem is reported we will try to address the issue in a timely fashion.

• Networking problems should be reported via email to net-admin@slac.stanford.edu. See Reporting Network Problems at http://www.slac.stanford.edu/comp/net/problem-reporting.html for the type of information to report.
• Since the visitor network does not have mission critical applications (see above), there is usually no support for the visitor subnet outside normal working hours.
• If you are in the Guest House and you are using wireless, it is equivalent to Stanford Campus wireless. See also Wireless Networking at SLAC
• For other help you should contact your Desktop Administrator or see your SLAC sponsor if you are a visitor to SLAC.
