1 | This tiny patch to rbldns adds records for the root of the zone. That |
| 2 | is, if the rbldns zone is bad.example.com, with entries like |
| 3 | 3.0.0.127.bad.example.com, you can now also have A and TXT records for |
| 4 | plain bad.example.com. I did this for my korea.services.net zone, |
| 5 | since potential users keep typing korea.services.net into their web |
| 6 | browsers and expecting something useful to happen. |
| 7 | |
| 8 | There's one new record type in the data file, a line starting with an |
| 9 | exclamation point, in the same format as the colon record, e.g. |
| 10 | |
| 11 | !10.11.12.13:See http://bad.example.com |
| 12 | |
| 13 | (Unlike in a colon record, a $ at the end of the text isn't special.) |
| 14 | |
| 15 | No warranty expressed or implied. If you find bugs, feel free to fix |
| 16 | them. |
