DNS service for Resnet Users
Although Information Technology Services strongly discourages it, some Resnet subscribers want to set up servers. Subscribers must have a valid reason to request setting up a server and must submit a request prior to doing so.
If you request to set up a server, be aware that static IP addresses are not allowed on Resnet. Instead, you will be assigned a DNS name that resolves to your dynamically assigned IP address. If your request to host a server on Resnet is granted, you must abide by certain rules.
- You must continue to use DHCP. Once your DNS is set up, you will have to renew your lease.
- DNS names cannot contain any identifying information such as student name, room number, ID number, etc.
- DNS entries are removed at the end of the summer session and the spring session.
- Only one name may be registered for each port, and you must register from the server on that outlet.
- DNS names will work only on the 1st-class service bracket. If your account is moved to the 2nd-class service bracket, requests for the DNS name will no longer resolve, and the server will not be accessible.
Note: When hosting a server, it is important to make sure you have enough bandwidth, and check your Port Status regularly to track your bandwidth usage. Typically, bandwidth limitations are only exceeded by servers trafficking in stolen intellectual property.
Making a request
To request to host a server on Resnet, send a request to email@example.com. The subject of the message should be "DNS Request" and the body of the message must contain the following information:
- Your full name
- Your port number
- The MAC address of the machine on that outlet
- Your phone number
- The reason you need a static hostname (this must be a real reason!)
- The hostname you would like (it will become yourhostname.dorm.utexas.edu)
Be aware that a response may take several days.
