Question Network mapper based on zone files ?

Good morning,

Say I have a zone file like this:
Code:
ns.chicago.company.com.      86400   IN      A       212.168.12.15
ns.casper.company.com.      86400   IN      A       212.168.14.15
company.com.               86400   IN      NS      ns.aux.company.com.
ns.aux.company.com.   86400   IN      A       148.106.119.1
company.com.               86400   IN      NS      secondary.company.com.
company.com.               86400   IN      NS      ns1.hostone.com.
company.com.               86400   IN      NS      ns2.hostone.com.
company.com.               86400   IN      NS      ns3.hostone.com.
company.com.               86400   IN      MX      10 mail.company.com.
company.com.               86400   IN      MX      30 mail2.company.com.
tma.company.com.          86400   IN      NS      dns.cci.company.com.

I am looking for network-mapper type software that would read the zone file and produce a graphical representation (Visio-style) of the network, along with IP addresses and respective ranges.

This is to have a clearer view of the whole network setup.
For instance, I would like to have a breakdown of all hosts by IP range.
Basically, I would need to resolve hostname entries (based on zone file records or ripe/arin) then join together the hosts that belong to the same range.

Classic network mapper applications are not suitable for my need as they are based on host discovery techniques and run on your LAN.
This is for a somewhat large organization and they use a couple subdomains too. I also have several zones for the subdomains.
The organization has presence in a few countries and owns a few IP blocks, and a number of websites are also with webhosts.

I was wondering if I could possibly get software recommendations to get the job done Smilie
I was going to write some bash but maybe there is no need to reinvent the wheel Smilie

Thanks Smilie

BIND2CSV2(1)							 MaraDNS reference						      BIND2CSV2(1)

NAME
bind2csv2 - convert zone files from BIND to MaraDNS compatible format DESCRPTION
MaraDNS 1.3 has BIND zone file support. This means it is possible to use BIND zone files in MaraDNS. This makes it easier for people to use MaraDNS in mixed DNS server environments. Instead of having direct BIND zone file support, MaraDNS has a script, called bind2csv2, that converts BIND zone files in to the "csv2" zone file format that MaraDNS 1.2 and 1.3 use. The zone files generated by bind2csv2 are not MaraDNS 1.2 compatible; MaraDNS 1.3 is needed to read zone files generated by bind2csv2. bind2csv2 is a Python script, written in version 2.2.3 of the Python interpreter. The script should be compatible with more recent versions of Python. The script assumes Python is the file /usr/bin/python on your system; if Python is located elsewhere on your system, please change the first line of bind2csv2. Naturally, you will need the Python interpreter installed on your system to use bind2csv2. This is a well-known open source language supported by most modern Linux and BSD distributions. USAGE
To use the script, enter a directory containing BIND zone files, and invoke the script thusly: bind2csv2 -c zone1 zone2 zone3 Substitute "zone1", "zone2", and "zone3" with a list of one or more BIND zone files you wish be converted in to MaraDNS 1.3 csv2 zone files. Once the script is run, you should have files with names like "zone1.csv2", "zone2.csv2", and "zone3.csv2". These files are csv2 zone files that MaraDNS will be able to parse. Copy these csv2 zone files to a place where MaraDNS can find the zone files. Should there already be a "zone1.csv2" file when bind2csv2 is run, the "zone1.csv2" file will be replaced. OPTIONS
None. Bind2csv2 can only be used as above. BUGS
bind2csv2 is not a perfect zone file converter. In particular, bind2csv2 does not act like BIND when NS records have different TTLs. Please make sure all NS records in your BIND zone files have the same TTL. In addition, bind2csv2 also does not support all resource record types that BIND supports. Only the following RRs are supported by bind2csv2: A AAAA AFSDB CNAME GPOS HINFO ISDN LOC MB MD MF MG MINFO MR MX NS NSAP PTR PX RP RT SOA SPF SRV TXT WKS X25 MARADNS
