The campus DHCP service will issue a lease for an IP address from a dynamic pool to any registered device. For this reason, it does not make sense to use departmental, or other specific subdomains for the DNS records of IP addresses in dynamic pools. The LIPS.Berkeley.EDU subdomain is used as a general container for DNS records for all IP addresses in dynamic pools, just like AirBears.Berkeley.EDU is used as a container for IP addresses used by AirBears clients. The campus DHCP service used to be called the Laptop IP Service, hence the subdomain LIPS.Berkeley.EDU. Fixed assignment of an IP address is generally restricted to one MAC address (and therefore one device). In this case, a departmental or other specific subdomain is used wherever possible for the associated DNS. Upon request, an existing or new hostname may be used instead of a default identifier. Contact the campus Hostmaster for DNS requests and questions related to fixed assignment of IP addresses via DHCP.
