IP Address Allocation Types - Static vs. Dynamic (DHCP) Reserved

BlueCat provides the IP address allocation option of Dynamic (DHCP) Reserved Addresses. By selecting Dynamic Reserved Addresses instead of Static IP when choosing an address allocation type, Proteus will provide the device with an address automatically via DHCP. If you select Static IP, you'll have to configure the device with the IP address manually. Selecting DHCP Reserved is the preferred process, unless the same MAC address must be assigned multiple IP addresses in the SAME subnet.

What is a CNAME Record?

A CNAME record, or Canonical Name Resource Record (RR), creates an alias for a fully qualified domain name (FQDN) in the DNS database. This allows one name to always resolve to the IP address specified by another name. For example, www.example.com can point to example.com. In order to create a CNAME RR, no other RR may exist with the same name (ex. an MX or NS RR).

Internal Records vs. External Records

There are two kinds of DNS Records we use here at Tufts: Internal and External. Internal DNS Records are records that can only be used while on the Tufts network. External Records are those that can be used while outside the Tufts Network. If you create only an Internal Record for a system, the domain name will not be accessible from the internet so you will usually want to use both.

Creating a CNAME Record

1.) Click the DNS tab at the top of the page. The DNS screen will open.

First2.) Next, click either internal the external view or external internal view. If the record needs to be in both views, you will need to repeat this process. Next, continue clicking

3.) Click to expand and drill down the domain tree (Tree View will be easier to use than Table View). Locate and open the DNS zone that you want need to create the record in.

Note: Tree view might be easier to use than Table View
When 4.) Once you're in the correct zone (ex. uit.tufts.edu) click the New menu, then select Alias Record. The New Alias Record Screen Appears screen will open.

Fill in the Name text box (ex. www.uittrain17.uit.tufts. edu) and the Host text box (ex. uittrain17.uit.tufts.edu) and wait for it to auto-complete. The CNAME Record must point to another name managed by Tufts.
Then, click the Add button. If you have more than one CNAME Record to create, click the Add Next button instead for a blank New Alias Record Screen. Changing a DNS Name
To change a DNS Name, first, search for the DNS Name or navigate to it via the DNS tab.
Next, at the top, click the DNS Name to bring up a menu, then click the Rename option.

The Rename Resource Record screen appears.
