It sounds like I can ignore these two. > auth = 1 if your data is authoritative for the zone and 0 if not. > usually you should set this to 1. setting it 0 will put the data into > additional section. Hmm. ISTR that answers were having their additional section populated automatically even though I wasn't setting "auth" to anything. Will double check that later. But it's good to know that's what the intention of the variable is at least. > scopeMask = how many bits of requestor IP was used to produce this > result. this should 0 unless you are using the client's (real) IP > somehow to come up with the answer, and if you do, how many bits of the > value was used. 128 (v6) or 32 (v4) means you used up the whole IP, 0 > means no bits were used. This sounds like it will work if I want to for example return a different A record depending on the source IP address. However, what if I want to return a specific A record for some source IPs, and *no* A record for other IPs? How do I set a scopeMask on an empty response? -- Mike Cardwell https://grepular.com https://emailprivacytester.com OpenPGP Key 35BC AF1D 3AA2 1F84 3DC3 B0CF 70A5 F512 0018 461F XMPP OTR Key 8924 B06A 7917 AAF3 DBB1 BF1B 295C 3C78 3EF1 46B4
