DHCP

Dynamic Host Configuration Protocol (DHCP) is a TCP/IP standard used to dynamically assign IP addresses to computers, so that they can communicate with other network services. A central network server distributes configuration information including IP addresses, DNS servers, subnet mask, and gateways.

Cornell offers a campus-wide DHCP server at no charge. More about DHCP

DNS

Domain name system (DNS) servers maintain a list of IP addresses and corresponding names for all the servers on the Internet. Your computer has to be able to connect to a DNS server in order for you to be able to use the Internet. For more information about how DNS servers work, see the DNS Wikipedia page. 

Cornell's domain name system (DNS) servers have the following IP addresses:

  • dns1 = 128.253.180.2
  • dns2 = 192.35.82.50
  • dns3 = 132.236.56.250
