• Search for: This field specifies the type of object(s) searched for. It can be owner (searching for owners respectively), block (searching for divisible block, address block delegated block types), or host. To search for both blocks and hosts simultaenously, without owner results, search type address is available.
• IP type: Select either IPv4 or IPv6. This field is ignored when searching for owners.
• Address: Type an IP address to be searched for. You may use wildcards, for example 192.* will show every address and/or block that begins with 192. This field is ignored when searching owners.
• Bitmask: The bitmask to be searched. Again, wildcard can be used. This field is ignored when searching owners or hosts.
• Owner's Name: The owner of the object(s) to be searched for.
• Subnet Status: This selection defines whether the block you are searching for is an ordinary block or a subnet. This field is ignored when searching owners or hosts.
• Information field: Wildcard accepting free text search for information field names.
• Information value: Wildcard accepting free text search for information field values.
• Case insensitive: The search is set as case insensitive by default, uncheck the box if you want your search to be case sensitive.
• DNS name filter: If a non-wildcard value is given for DNS name search filter, only Host entries matching the given DNS filter value will be returned. By default, the search is done in the default view, a specific view may be requested by adding @-sign and view name pattern after the domain name pattern entry. To search in all views, including the default view, add * wildcard right after domain name, without using the @-sign. This field is ignored when searching for owners or blocks.

It should be noted, that on wildcard and address search types, search will ignore the values in such fields that are not relevant for an object type - e.g. all matching owners will be returned even when there is no matching block owned by that owner for given IP restrictions. And address pattern matching will find host IP addresses even when they don't exist in a block that matches given bitmask or subnet type restrictions.
