I recently had the need to add a couple of thousand host objects to our Infoblox IPAM solution since we were missing almost all our store routers, switches, wireless switches, APC UPS, printers, etc. With over 500+ stores and not having any interns available I wasn’t looking forward to the challenge of navigating the WEB UI within Infoblox to create over 2,500+ objects. Instead I decided to let the computer do the work and I wrote a quick and dirty little Perl script that could essentially loop over the subnets in a /16 network and create the host objects for each device one at a time. This isn’t particularly pretty but it got the job done for me and I’m posting it here in hopes that it will help someone else traveling the same path.
I started with the following cURL request since I needed to know what format the data had to be in;
curl -k1 -u username:password -H "Content-Type: application/json" -X POST https://infoblox.acme.com/wapi/v2.1/record:host -d '{"ipv4addrs":[{"ipv4addr":"10.1.1.250"}],"name":"store1-printer.acme.com","comment":"HP LaserJet Printer"}'
That cURL request would create a host object at 10.1.1.250 with the name of store1-printer.acme.com. I took that structure, and built some Perl code around it and got the following script;
#!/usr/bin/perl
#
# Filename: /usr/local/etc/infoblox-rest.pl
#
# Purpose: Perl code to create Infoblox host objects utilizing REST API
# interface. Used to create DNS objects across multiple subnets.
# This code will create host objects for all the routers, switches,
# APC UPS, servers, PC, etc. Since the IP address of those devices
# utilize the same last octect in each IP subnet and there is a
# standard naming convention to easily follow programatically.
#
# Notes: This code is really just an example of what's possible using
# the Infoblox REST API interface. I don't expect anyone to actually
# use this code directly, but hopefully they will learn how to
# use the REST API interface in Perl through this example.
