Add multiple entries for TXT record in BIND

Hello Folks,

 

I have an existing TXT record for my domain abc.com. As per our security team we have to add an extra token to the TXT record to inform that we actually own the domain. Unsure how to add it. Should i create a new record or can it be appended to existing record. Please advise.

 

Eg : Existing record : "v=spf1 a mx ptr ip4:65.49.39.200/29" , new string : DZC=DlaVBmG

 

Regards, Anoop

    You have two options:

     

    1. Simply add multiple TXT records under ZoneRunner or directly into the zone file with the same name. e.g.

       

      • IN TXT "v=spf1 a mx ptr ip4:65.49.39.200/29"
      • IN TXT "DZC=DlaVBmG"

    2. Update the existing record with a space between the values e.g.

       

      • IN TXT "v=spf1 a mx ptr ip4:65.49.39.200/29 DZC=DlaVBmG"

    As long as you do not have multiple values within either a single record or across mulitple records e.g. you cannot have two records both containing "v=spf1", you should avoid conflicts .
