ccSLD (Country Code Second Level Domain)

ccSLD is the abbreviation for “Country Code Second Level Domain” and refers to a domain extension with an additional prefix in front of the ccTLD.  For example, .uk is a ccTLD and .co.uk is the ccSLD, (although due its popularity it is often incorrectly referred to as a ccTLD!  Confused yet?).  Many countries use .co.xx as the second level domain, many others use .com.xx.  There is no official standard, so you can find many variations on this format including net.xx, gov.xx, org.xx, police.xx, sch.xx, etc.  Other countries have no ccSLD at all, and provide registrations directly under the main ccTLD (such as .ws).
