I sent an email inadvertently to "comast.net". Does Comcast own that domain? If so, how do I get that email back? If it doesn't own it, who does and what is their contact information?
I don't think "comast.net" exists. But even if it did, once you send an email there is no way to retrieve it.
You can check domains and specifically 'comast.net' at https://www.whois.com/whois/comast.net. It is currently registered in Seoul, Korea.
If there was an email server at that domain and the email address you sent to was invalid, I would suspect you would get an 'undeliverable' response. If no email server, then I would think in just went into a black email hole.

No. Email sent to an @comast.net address is directed to mail servers "mx76.m2bp.com" or "mx76.mb1p.com", both operating on IP 188.8.131.52.
IP address 184.108.40.206 is assigned to IQuest Internet / LightBound LLC in Indianapolis, Indiana (see https://whois.arin.net/rest/net/NET-206-53-224-0-1/pft?s=220.127.116.11).
You can try reaching the contact info in those links, but I wouldn't expect too much. If you give it a try, please let us know what happens.

To look up email address domains, you need to check the MX records of the destination address. You can use tools like Window's "nslookup -type=MX comast.net", or like the "Email Dossier" page of https://centralops.net/co/.
