Reverse Delegation
|
Enables the use of MORE and LESS search level flag options to be used for
lookups on reverse delegation domains.
|
|
Inverse Attribute
|
Inverse queries are performed on inverse keys
available from the scroll list. The query when executed will return all objects
whose flag specified (from scroll list) attribute match the query argument
provided by the user.
|
|
IP Search Level
|
Users may require either an exact match to a
query or results based on more or less specific matches. To assist whois
users there is a set of flags that modify the response of the whois server.
These flags operate in the way described below.
[-x] Requests that only an exact match on a prefix be performed. If no exact
match is found then no results are returned
[-l] A LESS specific query option. Requests the server return not the exact
match but only the smallest of the IP ranges that is bigger than the user
supplied range and that fully contains it.
[-L] A LESS specific query option. Requests the server return the exact match
and all the objects containing information about IP ranges that are bigger
than the user supplied range and fully contain it.
[-m] A MORE specific query option. Requests the server return sub ranges
that are fully contained within the user provided range. However, instead
of returning all existing sub ranges, it will only return the biggest ranges
contained in the user range.
[-M] A MORE specific query option. Requests the server return all the sub
ranges completely contained within the user provided range.

Recursive Lookup
|
The options on the left had side do recursive look-ups on the whois database.
To disable this recursive look-up, use the "-r" option. This may be used
with the other option "-i"
A recursive query in the RIPE database retrieves related records, normally
contact information.
|
|
Primary Key
|
Requests that the objects primary
keys are to be returned. The exception are the set objects,
where the members attributes will also be returned.
|
|
Disable Domain Ref.
|
Switches off the use of the referral
mechanism for domain lookups, so that the database returns an object in the
RIPE whois database with the exact match of the query argument, instead of
doing a referral query.
The referral mechanism provides a way for administrators of domain registries
to instruct the whois server to reply to the user by fetching data from the
domain registry database rather than from local data. If a query to the whois
server results in the retrieval of a local object that contains a "refer:"
attribute, the server will connect to the remote server and issue a whois
query for the requested domain name. Whatever is returned as a result is
given back to the user.
|
|
Alternative Database
|
You can select a specific source database for information.
Or by selecting "ALL" databases you can search
each database that is mirrored by the RipeNCC.
|
|
Object Type
|
Restricts the types of objects to lookup in the query.
