Dotless Domains – A Unique Internet Phenomenon

Dotless domains refer to top-level domains (TLDs) that can be accessed directly without a second-level domain—like http://com/ instead of http://example.com/. While ICANN prohibits dotless domains on gTLDs, some country code TLDs (ccTLDs) still support them.

1️⃣ What Are Dotless Domains?

Dotless domains are TLDs that contain apex DNS records (A/AAAA or MX), allowing them to be accessed directly.

✅ Example:

• http://bd/ (Bangladesh .bd)

• https://uz/ (Uzbekistan .uz)

2️⃣ Why Are Dotless Domains Controversial?

Both ICANN and the IAB discourage dotless domains, citing security concerns.

✅ Key Issues:

• Confusion with local aliases – Some developers use foo.bar as test domains, which could conflict with real TLDs.

• Email limitations – SMTP requires at least two labels (domain.tld), making dotless email addresses impractical.

• Security risks – Dotless domains can be exploited for phishing or misconfiguration errors.

3️⃣ Dotless Domains in ccTLDs

Unlike gTLDs, ccTLDs operate under local jurisdiction, meaning some countries still allow dotless domains.

✅ Examples of Active Dotless ccTLDs:

• Bangladesh (.bd) – http://bd/

• Uzbekistan (.uz) – https://uz/

• Mongolia (.мон) – https://мон./

4️⃣ The Future of Dotless Domains

While ICANN prohibits dotless domains on new gTLDs, some ccTLDs continue to support them. The debate over their security and usability remains ongoing.

Final Thoughts

Dotless domains are a fascinating quirk of the internet, showcasing how DNS rules evolve across different regions.
