The common network components (BootP, DHCP, and DNS) are the functions for managing the networks through Internet Protocol (IP) assignment. Each computer or device in a network has its own identity, which is its IP address. Network administrators use IP addresses to manage and troubleshoot network services.

Details

BootP/DHCP

The DHCP (Dynamic Host Configuration Protocol) service provides automatic IP address assignment to computers and other network attached systems. BootP/DHCP also is used to assign of static IP addresses – addresses that need to remain the same. Printers that need to be allowed to send mail through LSMTP need a DHCP reservation as well.  Please note that while older procedures refer to it as a BOOTP reservation, it is a DHCP reservation; configure your device to use DHCP.  If the device is configured as a BOOTP client, it will not automatically assign the DNS and gateway settings.

DNS

The DNS (Domain Name System) is how domains named with words (example: “okstate.edu”) are translated into an IP address. Domain names using words are easier for people to remember than are strings of numbers (IP addresses), which is what digital systems use. A BOOTP reservation can be used to assign a Fully Qualified Domain Name (FQDN) to a device so it can be accessed by the FQDN rather than the IP address.  Note that any workstations joined to our domain will have an FQDN starting with the computer name and ending with ad.okstate.edu.

FAQs

  • How Do I Submit A Request For New Network Domain Name System (DNS) A Record?

    An A record or address record is a type of resource record in the Domain Name System (DNS) that is most used to map domain names to an IP address of the computer hosting the domain. A fully qualified domain name (FQDN) is a domain name specified with all labels in the hierarchy of the DNS, having no parts omitted. OSU uses FQDNs to identify department and sub-department domains such as su.okstate.edu for the Student Union, uhs.okstate.edu for Student Health Services, or it.okstate.edu for Information Technology. Contact the IT Helpdesk to request the creation of a new A record via one of the two options below:

     

    1. Submit a new request by authenticating to the New Network Domain Name System (DNS) A Record form.
    2. Start a support ticket by using this link: IT Request Help website.
      1. Include the following information in the Issue Field:
        1. Your Phone Number
        2. Affiliated campus name
        3. A Record Fully Qualified Domain Name (FQDN)
        4. A Record Fully Qualified Domain Name (FQDN) IP Address
  • How Do I Submit A Request For A New Network Domain Name System (DNS) CNAME Record?

    CNAME record or Canonical Name record is a type of resource record in the Domain Name System (DNS) specifying the domain name is an alias of or pointing to the IP address of another canonical domain name. A fully qualified domain name (FQDN) is a domain name specified with all labels in the hierarchy of the DNS, having no parts omitted. OSU uses FQDNs to identify department and sub-department domains such as su.okstate.edu for the Student Union, uhs.okstate.edu for Student Health Services, or it.okstate.edu for Information Technology. Contact the IT Helpdesk to request the creation of a new CNAME record via one of the two options below:

     

    1. Submit a new request by authenticating to the New Network Domain Name System (DNS) CNAME Record form.
    2. Start a support ticket by using this link: IT Request Help website.
      1. Include the following information in the Issue Field:
        1. Your Phone Number
        2. Affiliated campus name
