.vn is the country code top-level domain (ccTLD) for Vietnam.

The domain name registry for .vn is the Vietnam Internet Network Information Center (VNNIC).

Currently, the national domain name server system of Vietnam consists of seven server clusters. Among these, five clusters are located domestically, and two clusters are located in other countries, with more than 70 points in major cities around the world where there is a high density of .vn domain queries and a significant Vietnamese community.

.vn domain names with 1 or 2 characters are registered through an auction.

There are 43 1-character .vn domain names, including: 36 domain names with a plain ASCII character (a, b, c, .. .x, y, z, 0, 1, 2, 3, .. 7, 8, 9.vn) and 7 domain names with a Vietnam-specific character (â, ă, đ, ê, ô, ơ, ư.vn). There are 1296 2-character domain names with a combination of ASCII characters (a0, a1, a2, ..., z7, z8, z9.vn).

History
In 1994, Rob Hurle was one of the first to think of and be authorized to register the .vn domain for Vietnam, replacing the .au (Australia) domain. VNPT managed the DNS server and the .vn domain.

In 2000, VNPT transferred the DNS server and the .vn domain to the Vietnam Internet Network Information Center (VNNIC) when this center was established by the Vietnamese government.

In 2003, Dot VN, Inc. signed an agreement with VNNIC allowing the company to market the .vn domain overseas.
