"Dotless domains" are domains that consist of a single label (e.g. http://ai/, as opposed to http://example.ai/; or contact@pa as opposed to contact@example.pa) due to there being A/AAAA or MX records in the apex of a TLD zone.[1]
ICANN is notoriously against the practice,[1] and prohibits it where it can – namely, on gTLDs.[3] However, ccTLDs are under the country's jurisdiction, so it can do as it pleases, and as such there are examples of active dotless ccTLD domains.
For email, the protocol itself would need to allow a dotless domain as a destination address. According to ICANN's SSAC,[1] SMTP requires at least two labels (i.e. "domain.tld") to deliver an email, so it is unlikely Panama would receive an email sent to [email protected], for example. For completeness' sake, however, apex MX servers are listed below as well.

# New TLDs
In order to prevent local aliases from colliding with newly registered TLDs (think programmers using foo.bar as a test domain before the creation of the gTLD .bar), ICANN published a resolution in 2014 requiring new TLDs to include a few apex DNS records on their TLDs for at least 90 days.[4]
As such, as of January 2022, the following TLDs also contain apex records, but they're merely informational and don't point to real servers:
TLD | IP (A/AAAA) |
Email server (MX) |
Text record (TXT) |
---|---|---|---|
.arab | 127.0.53.53 | your-dns-needs-immediate-attention.arab | "Your DNS configuration needs immediate attention see https://icann.org/namecollision" |
.kids | your-dns-needs-immediate-attention.kids | ||
.music | your-dns-needs-immediate-attention.music |
# Historical
These are TLDs that previously had apex records, but no longer do so. The bulk of it comes from a list by the IETF from 2013:
