== File ==

'''Name:''' ''preferencesKad.dat''

'''Location:''' ''~/.aMule/''

== Description ==

This file stores the [[IP]] and [[Kademlia]] [[ClientID]].

== Format ==

The file format is as follows:

*''IP'': Stores the [client]]'s IP (4 bytes)
*''Deprecated field'': This field is no more used, so it's filled with 0s (2 bytes)
*''ClientID'': The client's ClientID (16 bytes)
*''End of tags signal'': Old [[eMule]] clients expected more info to be read on this file. To remain compatible with those clients, this field is set to 0 (1 byte)

Once this data is put together, it is stored in little-endian.

== Example ==

The following is a hex dump of an hypothetic ''preferencesKad.dat'' file:

''000000000000C1A3CBE82BBD354A398A7B623E100EBF00''

In the above example, the following data can be seen:

*IP: ''0.0.0.0'', which means it's not yet set (In hex: ''0x00000000'')
*Deprecated field: ''0'' (In hex: ''0x0000'')
*ClientID: ''C1A3CBE82BBD354A398A7B623E100EBF''
*End of tags signal: ''0'' (In hex: ''0x00'')

== Extra ==

[[aMule]] ignores the ''End of tags signal'' when reading this file, so it is optional to use it. Anyway, [[aMule]] does write it to keep compatibility with old [[eMule]] clients.

-Once this data is put together, it is stored in little-endian.
+Reading and writing the ''ClientID'' is somewhat tricky. It is stored as four 32bit little-endian integers, which themselves represent the 128bit value in big-endian order. See the example below.
