.SU was the country code top-level domain name assigned to the Soviet Union in 1990. Although the Soviet Union was officially dissolved in 1991, the domain name has been maintained and is still in use today. However, because the .su domain is less tightly regulated than other top-level domain names, the .su domain has attracted hackers, scammers, and cyber criminals. Of course, not all of the .su sites are malicious; legitimate .su sites exist as well.
(Note: .ru is the country code top-level domain name that is currently assigned to Russia.)

What is a URL?
The acronym URL stands for Uniform Resource Locator. Examining a URL can help you learn something about a website's origin, authority, and purpose.
A URL is essentially a reference (or address) to a website's unique location on the Internet. A URL is made up of several parts, and even if you're not familiar with the term "URL," you're probably already familiar with its basic structure. The following are examples of simple URLs:
One important part of a URL is the domain name. A domain name is an ID string that groups together locations on the Internet that either share a common affiliation (such as a commercial or geographic affiliation), or which are under the control of a particular organization or individual. In the examples below, the top level domain names are written in red.
What can a domain name tell you?
The most common top-level domain names in the U.S. are:

The purpose of .gov sites is to inform, teach, post public documents, present statistics or other research findings, and support the agencies and services of the United States government. Example: https://www.cdc.gov/ (Centers for Disease Control and Prevention) NOTE: many government websites will not have a single author listed.
.mil: short for military.
The .mil domain name is used by the agencies, services, and organizations which belong to the United States Department of Defense.The purpose of .mil sites is to support the agencies, services, and divisions of the United States Military. Example: http://www.norad.mil/ (NORAD)

.com: short for commercial.
The .com domain name is used by commercial entities, such as companies or private corporations. The purpose of .com sites is often to promote a product or a service, but it can be used very broadly by many different entities and organizations, such as news organizations.
