Using FIELD edns0, you can set, append, or replace specific EDNS0 options on the request.
 | 
			
		||||
 | 
			
		||||
* `replace` will modify any matching (what that means may vary based on EDNS0 type) option with the specified option
 | 
			
		||||
* `append` will add the option regardless of what options already exist
 | 
			
		||||
* `replace` will modify any "matching" option with the specified option. The criteria for "matching" varies based on EDNS0 type.
 | 
			
		||||
* `append` will add the option only if no matching option exists
 | 
			
		||||
* `set` will modify a matching option or add one if none is found
 | 
			
		||||
 | 
			
		||||
Currently supported are `EDNS0_LOCAL`, `EDNS0_NSID` and `EDNS0_SUBNET`.
