用perl实现的dns解析服务器程序“Net::DNS”

What is Net::DNS

Net::DNS is a DNS resolver implemented in Perl. It allows the programmer to perform nearly any type of DNS query from a Perl script. For details and examples, please read the Net::DNS manual pages. To read about the latest features, see the Changes file. To discuss and share experiences with other users of Net::DNS, subscribe to the mailing-list.

Net::DNS does not depend on any C libraries. However, if possible Net::DNS tries to link to the libresolv library. This provides a notable speed increase.

The author invites feedback on Net::DNS. If there's something you'd like to have added, please let me know. If you find a bug, please follow the instructions below.

The current release version of Net::DNS is: 1.20

New releases and developments are announced on the "Blog" (which is syndicated through an RSS feed).

Net::DNS::SEC

In case you would like to add DNSSEC support to Net::DNS please check out Net::DNS::SEC, an add-on to this package, available thought CPAN

Net::DNS::SEC is tightly integrated with Net::DNS but distributed separately because its dependency on libraries that may not port to all platforms.

The current release version of Net::DNS::SEC is: 1.12.

New releases and developments are announced on the same "Blog" as Net::DNS.

Bugs?

If you have a bug report, drop it by CPAN's RT installation. Your problem will be assigned a ticketnumber and can be tracked.

Here's a direct link to the Net::DNS bug reporting form.

If you find a bug, please report it to the author along with the following information:

• version of Perl (output of 'perl -V' is best)
• version of Net::DNS
• operating system type and version
• version of nameserver (if known)
• exact text of error message or description of problem
• the shortest possible program that exhibits the problem
• the specific queries you're making, if the data is available to Internet nameservers

If I don't have access to a system similar to yours, I may ask you to insert some debugging lines and report back on the results. The more help and information you can provide, the better.

Packages

Several operating systems provide a Net::DNS package. An incomplete list of those packages is available.

Rob Brown was nice enough to make some RPMs of Net::DNS.
