Is a .gw 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 .gw, so the extension is signed and anchored. A domain under .gw 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. .gw is the country code for Guinea-Bissau; its registry sets who can register.
IDN names under .gw
The registry publishes IDN tables at IANA for 1 scripts or languages, so names can use these characters (stored as xn-- in the DNS):
- Latin Script
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. There is no classic WHOIS server (port 43): since January 2025 ICANN lets gTLD registries offer RDAP only.
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.
