.cd为刚果民主共和国国家及地区顶级域（ccTLD）的域名。

英文释义：

.cd is the Internet country code top-level domain (ccTLD) for the Democratic Republic of Congo. It was created in 1997 as a replacement for the .zr (Zaire) ccTLD, which was phased out and eventually deleted in 2001.

Except for reserved names like .com.cd, .net.cd, .org.cd and others, any person in the world can register a .cd domain for a fee.
