Is a .sb 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 .sb, so the extension is signed and anchored. A domain under .sb 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. .sb is the country code for Solomon Islands; its registry sets who can register.
Second-level suffixes under .sb (5)
You can register names directly under .sb or under these suffixes, for example example.com.sb. Some are restricted to certain users (government, education, banks). Source: the Public Suffix List.
- .com.sb
- .edu.sb
- .gov.sb
- .net.sb
- .org.sb
IDN names under .sb
No IDN tables for .sb 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
This extension is not in IANA's RDAP list. Classic WHOIS (port 43) answers at whois.nic.net.sb.
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: http://www.nic.net.sb/.
