RFC1035 imposes a 255 character limit per string on TXT records .
- mjl- 2y agoYes, so you use multiple strings (in a single record) if you need longer values: "first 255 bytes" "second 255 bytes" "etc" DNS clients combine the 255-byte strings back into a single string.
- teddyh 2y ago> DNS clients combine the 255-byte strings back into a single string. No, DKIM clients and SPF clients do that. Generic DNS clients, however, are in theory free to ascribe any semantic meaning they like to the string separations.
