Internal and External Instructions
External DNS Change Directions
Two primary records need to be changed. The first is the ROOT record, this can be either empty or an @ record depending on your DNS host.
1. The first is the ROOT record, which needs to be an “A RECORD” or an “Alias” Record and it will need to point to our Amazon AWS servers at 54.208.31.49.
2. The second is the WWW record, this will need to be a CNAME record pointing to lb.gabbart.com”.
If you already have a WWW record that is not a CNAME record, then you will need to delete it before creating the new record.
3. The final step is to update any other URLs that are pointing to your campus websites. These will need to be set up as CNAME records pointing to “lb.gabbart.com”.
If these records are currently “A RECORDS” they will need to be removed before adding the CNAME record.
ONLY MODIFY "A" OR "CNAME" RECORDS
Schools who have Internal DNS Servers MUST make changes on their internal DNS server on their local network. Please see INTERNAL DNS CHANGE DIRECTIONS for additional instructions.
Making the Change on DNS Servers: Most Internet Service Providers (ISPs) for school districts will provide DNS servers to their clients. If this is your case, you will need to contact them and request the DNS Changes listed above. However, if you own your own domain name and are using DNS servers provided by Network Solutions, GoDaddy, etc., you will need to log into your account and make the appropriate changes.
Internal DNS Change
Schools with an Internal DNS Server MUST make changes on their local network.
Find DNS Server In Windows XP:
Go to a COMMAND PROMPT by clicking START, then click RUN, and type CMD in the box.
A DOS COMMAND PROMPT (Black Windows with blinking cursor) will open.
Type IFCONFIG /ALL.
A list of information will load. Look for DNS Servers.
Write down the IP addresses of these servers. They should begin with a 172 or 192,
or 10.
If it’s pointing to any other number, you are using an outside the school DNS server and it will need to be updated through your External DNS instructions above.
Find DNS Server In Windows 7:
Go to a COMMAND PROMPT by clicking START and type CMD in the box at the bottom.
A DOS COMMAND PROMPT (Black Windows with blinking cursor) will open.
Type IFCONFIG /ALL. A list of information will load.
Look for DNS Servers.
Write down the IP addresses of these servers. They should begin with a 172, or 192, or 10.
If it’s pointing to any other number, you are using an outside the school DNS server and it will need to be updated through your External DNS instructions above.
Making Changes on DNS Server:
Either go to your DNS Server or use Remote Desktop to access the DNS Server IP address found above.
You MUST know the Network Administrator Username and Password to access the server.
From the Server: Click START, ADMINISTRATIVE TOOLS, & DNS.
Click the PLUS signs next to the SERVER NAME, FORWARD LOOKUP ZONES, and then click on DOMAIN NAME.
On the right side, all computers on the local network will appear.
Click DATA in column header once or twice until the largest IP addresses appear. (Unless Network IP Range is 10.??.??.??, you will want the largest to appear on top.)
It will look like the picture below.
Find the entry with www under the NAME column.
Write down the IP address next to www for future reference.
Double click the line to edit. If it is not HOST (a) Record, change this to a HOST (CNAME) and point to “lb.gabbart.com”.
Next, search for the previous “written down” IP address.
If it appears anywhere else, please follow the same steps, unless the name is empty or “@“ then leave it as a HOST (A) and change the IP to 54.208.31.49.
