What is a “multi-string” TXT record?

TXT records have a 255-character limit per string. Longer content must be split:

Multi-string format:

"first 255 characters..." "next 255 characters..."

How it works: DNS stores multiple strings. Receivers concatenate them into one value.

When needed: Complex SPF records with many includes, or DKIM keys (especially 2048-bit) often exceed 255 characters.

Provider handling: Some DNS providers handle splitting automatically. Others require manual splitting. Some have bugs with multi-string records.

Common errors: Incorrect splitting, missing quotes, extra spaces between strings.

Long messages split across multiple pages, reassembled by the reader into the complete document.
