Begränsningar

## Domain Restrictions

- Name servers must be pre-configured and [registered with ISNIC](https://www.isnic.is/en/site/login)
- Following requirements for the name servers are obliged by the [registry](https://www.isnic.is/en/host/req):
- The nameservers must be registered with ISNIC.
- Nameservers must allow connection to UDP port 53, and to TCP port 53 as well (see [RFC5966](http://www.ietf.org/rfc/rfc5966.txt?number=5966))
- SOA records must be correctly formatted:
- Master nameserver correctly named in the MNAME field.
- Working mailbox of responsible party in RNAME field.
- Times (refresh, retry and expire) according to [RFC1912](http://www.ietf.org/rfc/rfc1912.txt?number=1912)
- TTL for NS records not lower than 24 hours.
- Correct NS records. Properly registered in the appropriate zones, both forward and reverse. I.e. the nameserver's name must be included in the PTR record set for the nameserver's IP address.
- Zone check tool is available at [https://www.isnic.is/en/host/test](https://www.isnic.is/en/host/test)
- _is_ registrants may use the RRPproxy nameservers in the future, if they cannot provide their own name servers that meet the requirements of the registry (special configuration, registration of the used name servers at the registry). If the name servers are not configured correctly during domain name registration, the domain will be parked and will remain inactive. An error will occur, if the registrant tries to update a domain with an incorrect name server configuration.
- The usage of a role contact for owner and admin(e.g. Domain Administrator, Hostmaster etc.) is not allowed and will result in the suspension of the domain by ISNIC. in case of an organization, the company name can be splitted and used as first and last name.

Innan domänen registreras måste namnservrarna som domänen kommer att peka mot att skapas. SOA record måste finnas.

Namnservrar

Toppdomänen kräver att minst 2 namnservrar används samt max 4 stycken.

Nameserver Requirements

Nameservers hosting Icelandic domains (.IS domains) must comply with all of the following requirements:

Nameservers must allow connection to UDP port 53, and to TCP port 53 as well (see RFC5966).
Nameserver must be consistently registered in DNS, i.e. its own A resource record must be available and a corresponding PTR resource record as well.
Namesever name can only contain ascii letters, digits, hyphen and periods.
NS records need to have 86400 as TTL.
For nameservers within the .IS zone, the following also applies:
Hostname can not be numeric only (i.e. 123.isnic.is) (See: RFC1035 RFC1123 RFC1912 ).
The full name of the nameserver (FQN) must include the hostname (i.e. the canonical name of the machine the nameserver is running on).

Förnyelse

Domänen kan förnyas för följande perioder

I vissa fall går det att förnya domänen efter det att den förfallit.

Har domänen löpt ut kan den återställas för en extra kostnad. Det kan ske under en period av 30 dagar efter att domänen löpt ut, alternativt efter att grace period löpt ut. Denna kostnad är i regel ganska hög, kring 5000SEK.
