Availability: Macintosh.
This module provides an interface to the Macintosh Domain Name
Resolver. It is usually used in conjunction with the mactcp
module, to map hostnames to IP addresses. It may not be available in
all Mac Python versions.
The macdnr module defines the following functions:
- Open ([filename])
-
Open the domain name resolver extension. If filename is given it
should be the pathname of the extension, otherwise a default is
used. Normally, this call is not needed since the other calls will
open the extension automatically.
- Close ()
-
Close the resolver extension. Again, not needed for normal use.
- StrToAddr (hostname)
-
Look up the IP address for hostname. This call returns a dnr
result object of the ``address'' variation.
- AddrToName (addr)
-
Do a reverse lookup on the 32-bit integer IP-address
addr. Returns a dnr result object of the ``address'' variation.
- AddrToStr (addr)
-
Convert the 32-bit integer IP-address addr to a dotted-decimal
string. Returns the string.
- HInfo (hostname)
-
Query the nameservers for a
HInfo record for host
hostname. These records contain hardware and software
information about the machine in question (if they are available in
the first place). Returns a dnr result object of the ``hinfo''
variety.
- MXInfo (domain)
-
Query the nameservers for a mail exchanger for domain. This is
the hostname of a host willing to accept SMTP mail for the
given domain. Returns a dnr result object of the ``mx'' variety.
