Update .IS section

[groundcat]

I am creating this pull request to update the .IS block in the ICANN section.

Steps taken to verify information from the authoritative source:

1. Started at the IANA page: https://www.iana.org/domains/root/db/is.html and identified the registry website for registration services: https://www.isnic.is/
2. Located the email address provided on the registry website and sent an inquiry.
3. Received a direct reply from the domain registry (Marius Olafsson <[email protected]>), confirming the requested information.

Excerpt from the email confirmation:

> I?ve noticed that the .IS registry operates several second-level domains,

>   * is
>   * net.is
>   * com.is
>   * edu.is
>   * gov.is
>   * org.is
>   * int.is

ISNIC (the .IS registry) only operates .is -- the others above are
simply reserved to avoid confusion.

> For example, users can register domains like example.net.is and educational
> organizations can register example.edu.is.

No, they can not. These are reserved and not available for registation and thus
can not be operated as SLDs. Just type in e.g. 'x.edu.is' on https://www.isnic.is/en

Yes -- they are reserved and thus not registered in DNS.

> Could you please clarify the following:

They have never been available for registration. Have been reserved from the
establishment of the .IS domain in 1986.

>  2. Available Suffixes: Can you provide an updated list of all second-level

Only .IS is currently managed by the .IS registry.

These SLD have never been available for registration.

A complete copy of the email confirmation along with the email headers is available to be forwarded to a maintainer for review upon request.

This email did not contain any DKIM signature either. We will need to figure out how else to verify this.

I just emailed them back to ask if they can send an email directly to you. I also cc'd you on it.
