Is a .ss name registered?

Looked up from your browser in the registry's RDAP service; if that does not answer, in DNS. Nothing is stored on dnssec.in.

What this means

The root zone holds a DS record for .ss, so the extension is signed and anchored. A domain under .ss can use DNSSEC with a full chain of trust: it needs to be signed at its DNS host and have its own DS at the registrar. .ss is the country code for South Sudan; its registry sets who can register.

Second-level suffixes under .ss (9)

You can register names directly under .ss or under these suffixes, for example example.co.ss. Some are restricted to certain users (government, education, banks). Source: the Public Suffix List.

  • .biz.ss
  • .co.ss
  • .com.ss
  • .edu.ss
  • .gov.ss
  • .me.ss
  • .net.ss
  • .org.ss
  • .sch.ss

IDN names under .ss

No IDN tables for .ss at IANA: names are usually ASCII only (a–z, 0–9 and hyphen).

Length

DNS limits are the same everywhere: each label is 1 to 63 characters, the whole name at most 253, letters, digits and hyphens, not starting or ending with a hyphen. IDN labels count their xn-- form, so fewer native characters fit. A registry can set a higher minimum (often 2 or 3 characters) or reserve short names: that is in its own policy.

WHOIS and RDAP

RDAP (the JSON successor to WHOIS) answers at https://rdap.nic.ss/. Classic WHOIS (port 43) answers at whois.nic.ss.

Lifecycle and drop

Country code extensions set their own lifecycle: grace periods, redemption and release dates differ from country to country and are not covered by ICANN's gTLD policies. Read the registry's rules: https://nic.ss/.
