mkrdns is a small Perl script that helps automate changes to your DNS zone files. It does this by reading your named.boot/named.conf file to find all the domains/networks for which you are authoritative. It then reads all of the forward zone files and generates PTR records which it inserts in the reverse zone maps.
SendIP is a command-line tool to send arbitrary IP packets. It has a large number of options to specify the content of every header of a RIP, RIPng, BGP, TCP, UDP, ICMP, or raw IPv4/IPv6 packet. It also allows any data to be added to the packet. Checksums can be calculated automatically, but if you wish to send out wrong checksums, that is supported too.
JH2N (Java host to named conversion program) converts a hosts file to a full BIND 8 or 9 configuration. JH2N was inspired by the h2n.pl program included in the O'Reilly "DNS and BIND" book. Various options are available to enhance its operation by incuding external files. Using the simple host file syntax, very large and complex zones can be maintained.
adlook (Address Lookup tool) is a multi-threaded host name and technical contact lookup tool. It accepts a list of IP addresses from the command line, from a data file, or from stdin, and outputs the hostname and technical contact for each address. Although it is written in Python, for the time being it runs only on UNIX systems. Python must have been compiled with threads enabled to run adlook.
Dixie DNS & DHCP Config Tool is a Web interface written in PHP for configuring and administering ISC bind and dhcp. It maintains a database with general DNS and DHCP information, and information about subnets and hosts. It produces config files, or sends dynamic DNS updates if DDNS is used on the server. It has simple DNS and DHCP live browsers, and can produce subzone files for MS Active Directory.
