Networking provides Local Area Network (LAN) infrastructure and network connection support services to LBNL staff and research programs throughout the Lab. Wireless and other infrastructure services are also provided.
DNSLBLnet provides support for domain name requests and services.
FirewallsLBLnet, the data network within LBNL, is not protected by a conventional firewall, however certain ports are blocked by default at the Lab's network border. For details on these ports, please see the Perimeter Protection document.
IP Multicast SupportLBLnet supports IP Multicast on most user subnets (please call x4357 for more information).
IP Subnet Addresses at LBNLAddresses of IP Subnets at LBNL, NERSC and JGI.
LBLnet IP RequestThe IP request website allows the requester (an end user) to add new, change existing, or remove existing domain name system (DNS) records and update host contact information.
Network ConsultingNetworking offers various levels of help, from information to advising to detailed planning, helping to modify or add to existing setups at all levels, including large-scale changes or new additions to Berkeley Lab’s networks and services. The Consulting Service provides individuals and departments with technical expertise and network management experience, and the capacity to modify or expand the network infrastructure to meet special requirements.
Network Time ProtocolNTP (Network Time Protocol) is a means of transmitting time signals over a computer network. It is typically used to synchronize a computer’s time with reliable and geographically-close time sources.
Network TroubleshootingThe LBLnet infrastructure is monitored at all times by automated network management systems which notify LBLnet of network outages by pager. To report network problems that don't need immediate attention, please send email to firstname.lastname@example.org

IT has developed a specific page for information about telecommuting during the COVID-19 event. Please visit https://remotework.lbl.gov/
VPN (Virtual Private Network)A virtual private network, or VPN, is an encrypted connection over the Internet from a device to a network. The encrypted connection helps ensure that sensitive data is safely transmitted. It prevents unauthorized people from eavesdropping on the traffic and allows the user to conduct work remotely.
Wired NetworkingIT provides high speed wired network connections to the Laboratory. Most systems can just plug-in to a working jack and receive a Dynamic (DHCP) address.
