Connecting an MIT URL to an Outsourced Website

On this page:


If you've outsourced your web hosting, and you're working on behalf of an official DLC, you can request that we do a DNS mapping so that your site can be made visible under an MIT name.

If you've already got a website in your MIT name, and you're working on transferring it to new hosting, you will want to use Hostname Migration - Validation ahead of DNS change to validate this carefully ahead of time.

MIT will not delegate name server control (so no NS records) but we will provide CNAME and A records.

In general, look for language like "connect a domain" in your vendor's documentation or service descriptions to find out more about their offerings and processes for connecting an MIT URL to their web hosting services.

SSL/https certificates

Many commercial web hosting providers will also request an appropriate https certificate from Let's Encrypt, once your DNS has been transferred over - the process will often take about 30min to complete. We'll try to note below if we encounter any providers who don't do this smoothly.


  • Github Pages (

    You should establish a hostname for the entire site; we will not be able to work with a requested path that is
    Note also that we do not provide Github Pages functionality on our internal github ( - you must use the externally hosted github if you wish to host web content there.
    We will provide a single CNAME record:
    CNAME <mit sitename>
    See also: Using GitHub to Manage or Host an MIT Website

    We've had some additional issues with spammers managing to claim URLs mapped to; as a post-setup task, please consider also asking for the TXT record validation described here: Verify Custom Domain

  • Heroku

    There's several possible formats, but we will usually provide a CNAME to
    Please follow through enough with Heroku to get https certificates installed; this requires customer intervention.

  • Squarespace

    Connecting a Domain to Your Squarespace Site

    Squarespace requires multiple A records, for the primary name, plus a CNAME record for plus a verification code that will be [hd:some string of characters] as a CNAME to VERIFY.SQUARESPACE.COM. We need to be told what the unique verification code is, but everything else is stock. Client MUST supply the verification string as copied text - screen captures are not acceptable.

No Email Sending
Please be advised that Squarespace's email sending service is something we won't support/allow with email addresses; please use Squarespace as a website provider only.
  • Vercel

    We will provide a CNAME record and a validation record that looks like:
    Where you should copy and paste the exact code given.

  • WebFlow

    We will add a single CNAME record:
    CNAME <mit sitename>

  • Wix

    Wix Connecting a Domain You Purchased Elsewhere

    Additionally, we won't provide NS records, so from there you will need this option:
    Connecting a Domain to Wix Using Pointing

    Wix can provide the following information: an A record for, and a CNAME record for - the CNAME data is particular to the site in question and will be something like WWWnn.WIXDNS.NET, where nn is a two digit number. This information can be checked Escalatons team and by then relayed to IDE for an update of MIT's DNS records.

  • wpengine

    We will add a single CNAME record to, you will need to follow these instructions:

    wpengine Add Domain Site

  • Microsoft Azure (

    Free (F1) tier is not sufficient, need to upgrade to a paid tier. But name mapping by CNAME is available per:

    Azure Custom DNS Tutorial

  • GoDaddy

    Don't use GoDaddy
    We have had trouble getting this information from GoDaddy. Please avoid using GoDaddy, or proceed with extreme caution.
  • Other outsource providers not listed

    Look for documentation that matches to "connect a domain you already own" and "map a hostname". Steer away from a vendor who requires that they manage your DNS for you (or instructions for transferring your domain over to them). We're happy to update this documentation if you've successfully worked through this and have the links you used.

Making the request

We will need:

  • Staff or faculty member's contact information and permission/sponsorship.
  • A cost object (which won't be billed) to track it under.
  • The technical DNS details.
    Let us know at with all of the technical details in an organized manner.
Copy and Paste
Sometimes a screenshot helps us clarify the context of a situation, but if the vendor is asking for a validation string, please make sure that you also copy and paste that into the text of your question. It's not accurate or convenient to ask us to transcribe data out of a screenshot.

MIT owned web pages should comply with MIT's accessibility agreement; please take care of this on the remote website before making your request.

Follow Up

Leaving an MIT hostname attached to a broken or absent website is not acceptable. It's your responsibility to:

  • Complete any setup steps to attach the name fully in a timely manner
  • Keep your hosting account organized and paid up
  • Hand off hosting management to a suitable successor when you leave MIT
  • Comply with MIT's branding and accessibility policies
  • Inform us when you are done with the project.
