LBNL Main site (lbl.gov)
The LBNL main site uses an anycast address, back-ended by four nameservers, to handle dns requests depending on your location on the network. Using the anycast address provides automatic redundancy during maintenance periods on the nameservers. The vast majority of computers should use this anycast address and no second DNS server is required.
ALS uses an anycast address backed by two nameservers located on ALS subnets. Using the anycast address provides automatic redundancy during maintenance periods on the nameservers. All ALS computers should use this anycast address and no second DNS server is required.
Computers on the at the JGI Walnut Creek site space should use the same anycast address used at the LBNL Main site. The anycast server is backed by four nameservers including one physically at the JGI site.
If the computer is at NERSC in Oakland, please use this list of nameservers.
Caching Only Nameserver
If you are running a caching only nameserver on the LBNL Main network, it is recommended you forward to just ns.lbl.gov or nsals.lbl.gov.
