  3. no field MUST be shown.
  • If data exist for a given optional field, the key (field name) and the value with the data MUST be shown.
  • If no data exists in these optional fields, registrar MUST implement either of:
    1. the key (field name) MUST be shown with no information in the value section of the field; or
    2. no field MUST be shown.

Example:

Requirements on “Required ” Fields

...

  • Billing Contact, two acceptable places:
    1. Immediately after the field “Technical Contact”, or
    2. As additional fields that follows the last field “URL of the ICANN WHOIS Data Problem Reporting System”

Example:

 


Other Requirements

The following items’ numbering conform with the numbering in the Advisory:

4. If the registrar decides to provide translation to field names, the translation must be in parenthesis (U+0028 and U+0029), with Solidus between different translations, spaces should conform with the below example:

            Domain Name (域名名称/域名名稱): foo.example

5. All domain name labels in WHOIS (except the IDN Field), should display its ASCII form (A-Label), e.g. NS Record with an IDN domain name:

            Name Server: ns1.xn--caf-dma.example

8. The date and time shown in the footer

 “>>> Last update of WHOIS database: <date and time> <<<”

is the date and time in which the RDDS database was updated from the SRS database. In a case where the registrar is querying its own database, and therefore, using real-time data, this date and time will show the timestamp of the response to the query.

10. “DNSSEC: signedDelegation” MUST be shown when the domain name has one or more DS or DNSKEY records. "DNSSEC: unsigned" MUST be shown if the domain name is not signed.

17. There SHOULD NOT be empty lines between the last data field and the footer ">>> Last update of WHOIS database: <date and time> <<<". If shown, no more than three (3) empty lines are allowed.

18. WHOIS (port-43) queries for domain name objects SHOULD return only one record per query (i.e., no partial match or other search capabilities, only exact match lookup).

24/25. Except the following fields below, the other fields MUST NOT appear multiple times:

    1. Domain Status
    2. Name Server
    3. Registrant/Admin/Tech/Billing Street (EPP RFC 5733)

26. When a queried object does not exist, registrar SHOULD return the key “The queried object does not exist:”

    1. optionally followed by a registry-defined text message (the value) that provides more information about the non-existence of the object.
    2. No other fields MUST be shown.
    3. The "last update" footer, blank line, and legal disclaimer MUST follow as with other WHOIS queries.

46. The field “Registry Admin/Tech/Billing/Registrant ID:”, this information MUST be shown if available from the Registry. If this information is not available from the Registry (e.g., a "thin" registry), the string "Not Available From Registry" SHOULD be shown instead.

50. The following fields are not specified in the EPP RFCs: 5730-5734, or 3915, and MUST follow the below format specifications:

    1. "Registrar Abuse Contact Email" (RFC 5322)
    2. "Registrar Abuse Contact Phone" (ITU-T E.164)
    3. "Reseller" is defined as token (Extensible Markup Language 1.1)
    4. "Registrar WHOIS Server" value is defined as a hostname and is the server name of the (port-43) WHOIS server of the sponsoring Registrar
    5. "Registrar URL" value is defined as a URL (see RFC3986) and MUST show the website of the sponsoring registrar, more specifically, the URL of the web-WHOIS of the queried object, or at least the URL of the web-WHOIS service of the registrar
    6. "Registrar IANA ID" value must be a positive decimal integer.
    7. "Registrar" value is defined as token (Extensible Markup Language 1.1).
