[Twisted-Python] How to get the client ip when it ask a resolution with twisted.names
by contact＠benoit-laviale.fr 02 May '21

Dear all, I am working on twisted names since some days to make kind of filtering system (with domains blacklists). So I made my own resolver that can reply defer.fail(error.DomainError()) to send the query to the next resolver (and in this case, it will be resolve) or defer.fail(dns.AuthoritativeDomainError(query.name.name)) to reply NXDOMAIN that can "block" the domain to the final client. That part is working well. Next, i would like to "block" the resolution regarding the device (Mac address/IP/???). I would like something like that : if self.query.meta.client.ip == b"192.168.0.5" or self.query.meta.client.mac == "XX:YY:ZZ:....": self.do_something() My use case is that device of Kelly, (Kelly is a teenager of 12 years) cant use youtube.com at all, but other devices are allowed to get the resolution. How can I get the IP/Name/mac (an identifier) of the device that's querying my custom dns? I read something about datagrams, but in my case i think i must get this information in my resolver... Thx and cheers. Benoît
