The project is deprecated now and this repo has been archived. I moved to CoreDNS which is not only waaay faster, but covers all features pdnsapp had. Ok.. well, almost all. I had to develop some extra coredns plugins to port some niche features anyone would have barely needed on the long run.
This is a python microframework to help develop DNS-based applications, very much like bottle.py for HTML or lamsonproject for SMTP. It's 'application server' is PowerDNS.
The following code will resond with the IP-address of the querying client for myip.end.re
:
@match(fqdn='myip.end.re',type='A')
def myip(request):
return A(data=request['remote-ip'])
Be authoritative for all the zones. It's like wildcards on steroids. Or like PowerDNS superslave being a supermaster instead.
@match(type='SOA')
def catchall(request):
return SOA("ns0.end.re dnsadm2.end.re %s 10800 3600 604800 3600" % strftime("%Y%m%d%H"))
@match(type='NS')
def catchall(request):
return [
NS('ns0.end.re'),
NS('ns1.end.re'),
]
Simple geoip implementation, this one returns differenct IP address for mx0.end.re
depending on the client IP address.
from radix import Radix
rtree = Radix()
for subnet in ['192.168.0.0/24', '192.168.1.0/24']:
rtree.add(subnet)
@match(type='A', fqdn='mx0.end.re')
def geoip(request):
if rtree.search_best(request['remote-ip']): #if requesting client is in the prefixes listed
return A('192.168.1.1')
else:
return A('44.128.1.1')
This is for generating reverse (PTR) DNS entries and their forward (A/AAAA) lookup.
