.is WHOIS Lookup: Fields of an Icelandic Record
.is is the country code extension of Iceland and has been in the root zone since 18 November 1987. The registry is ISNIC (Internet á Íslandi hf.), whose server whois.isnic.is answers on port 43; an RDAP service runs at rdap.isnic.is as well. The root holds a DS record for .is, so the Icelandic zone is signed with DNSSEC.
An ISNIC reply opens with handles for five roles: registrant, administrative, technical, zone and billing. Each handle expands into its own contact block later in the same reply. The domain section also lists the name servers, a dnssec field and the creation and expiry dates, while a registrar field and a status line are absent. To compare it with another registry built on handles, open the .at WHOIS lookup.

WHOIS FAQ
How do I find out who owns a .is domain?
Follow the registrant handle in the WHOIS reply to its contact block, where ISNIC prints the holder's name, postal address, phone number and email. The RDAP record names the registrant too. The whois.com.tr result screen already fills the registrant field from this data, so you only need the handles when you want the full contact details.
When does a .is domain expire, and where is the date?
The expiry date of a .is domain is on the expires line, written with the month in English words, as in September 5 2027. Parsers that only expect numeric dates can skip or misread such lines, which is why some tools show empty dates for .is. The whois.com.tr result screen shows the creation and expiry dates as two separate fields.
What does soft expiration mean for a .is domain?
Soft expiration is the name ISNIC's RDAP service gives to the expiry event, and it carries the same date as the expires line on port 43. The wording presents the date as a threshold for renewal and does not say that the name is deleted the next day. Before you treat a .is name as free, query its record again once that date has passed.
What are the admin-c, tech-c, zone-c and billing-c lines in .is?
They are handles, short identifiers that point to the contacts for the administrative, technical, zone and billing roles. When the same handle appears in several roles, one organisation covers those duties together. RDAP shows such a shared contact once, with all its roles attached. Match each handle with its block to see who is responsible for what.
Is a .is domain signed with DNSSEC?
Whether a .is domain is signed shows in the dnssec field of its record, where signed delegation means a DS record for that name sits in the .is zone. Because the .is zone is signed as well, a validating resolver can follow the chain from the root down to that domain. The result screen reports this state as a field of its own. Not every country code is signed, as the .to WHOIS lookup shows.
How can I tell if a .is name can still be registered?
An unregistered .is name returns a reply with no handles and no dates, and the result screen marks it as available. A reply that lists a registrant handle means the name is taken, and ISNIC has assigned it to the person or organisation named in that handle's contact block.
