-A TXT record may have more than 255 characters of data, but **not** more than 255 characters in a single string, which is problematic for long chains like DKIM keys. RFC 4408 defines how to get around this limitation : a TXT record is allowed to contain multiple strings which should then be concatenated together by the reading application. TeemIP implements this concept through a chaining mechanism. TXT records with the **exact same** RR Name may be chained together. The tool that generate Zone data files will take the chain into consideration and will create the proper entry in the db file.+A TXT record may have more than 255 characters of data, but **not** more than 255 characters in a single string, which is problematic for long chains like DKIM keys.

 +<note tip>
 +When a segment is set in a given TXT record, its counter part is automatically updated.
 +  * If **Previous segment** of record R1 is set to R0, then TeemIP will set **Next segment** of record R0 to R1
 +  * If **Next segment** of record R1 is set to R2, then TeemIp will set **Previous segment** of record R2 to R1
 +</note>
 +<note warning>
 +In a chain, only the RR Name of the **first segment** is relevant. It is considered as the reference for the TXT Record when the db file is built. The name of the following records of the chain are just used to name the objects.
