This article relates to LoadMaster firmware version 7.2.52.
In LoadMaster firmware version 7.2.52, support for the TXT (Text) DNS record type was added to the GEO functionality. A TXT (text) record is essentially unformatted data that can be used for almost any purpose, but typically contain information to be consumed by clients to classify a domain in some way, provide details about a domain, or specify resources available within a domain.
You can configure a single, global TXT record by going to Global Balancing > Miscellaneous Params in the LoadMaster User Interface (UI). The configured record is returned for a TXT request on any Fully Qualified Domain Name (FQDN).
A maximum of 127 characters can be entered as the global TXT record.
The following are not supported as of firmware version 7.2.52:
- Multiple strings within the record: Some DNS providers allow you to put multiple strings in one entry using quotes, for example, "string 1" "string 2" "string 3". Kemp does not allow this as of firmware version 7.2.52, so you can only have "string 1", for example.
- Non-ASCII characters
