- | 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. | + | 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.

+ | 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 **Next segment** of record R0 will be set to R1 | ||
+ | * If **Next segment** of record R1 is set to R2, then **Previous segment** of record R2 will be set to R1 | ||
