No it doesn't. Those require a dot at the end. Without a dot, it's a hostname not a TLD.

- easrng 5y agoWithout a dot it won't always use the TLD. easrng@easrng-laptop:~$ echo -e "127.0.0.1\tai" | sudo tee -a /etc/hosts 127.0.0.1 ai easrng@easrng-laptop:~$ ping ai PING ai (127.0.0.1) 56(84) bytes of data. ^C easrng@easrng-laptop:~$ ping ai. PING ai (209.59.119.34) 56(84) bytes of data. ^C
- kingcharles 5y agoYou're right. I did some experiments too after your first reply. It's definitely inconsistent depending on what software you are using (as some software now bypasses your system resolver and uses HTTP DNS etc). I've known people who had email addresses on TLDs and they never had any problem receiving email (without using a final dot), so I'm not sure how the MX record is being resolved or how the SMTP connection is being made. It's very possible that the mail daemon is automatically adding a dot to the end of every hostname.
- tsimionescu 5y agoTechnically, without a dot at the end any domain name is a partially qualified domain name. Technically, 'gmail.com' should mean 'gmail.com.local.search.domain.' if your local search domain/zone is "local.search.domain."
