Quickly Add or Delete an Infoblox host entry.

by deaves

I was going through the published Infoblox /wapidoc documentation and decided to write a shell script that gives me the ability to bulk add/delete Infoblox HOST records at my office. This script uses cURL to post against an Infoblox grid master. You will need to make sure your user account has API permissions and the DNS zone association for the IPAM address range is configured to allow the particular domains host entries.

The following is the output of the script adding and deleting HOST records on an Infoblox in my lab.

Adding/Updating a HOST record

$ ibHOST.sh -u -h testing -i
D: "record:host/ZG5zLmhvc3QkLjEuY29tLnNweC5nbG9iYWwuZGUtdGVzdGluZw:testing.domain.contoso.com/Internal%20View"
U: "record:host/ZG5zLmhvc3QkLjEuY29tLnNweC5nbG9iYWwuZGUtdGVzdGluZw:testing.domain.contoso.com/Internal%20View"

$ host testing
testing.domain.contoso.com has address

Deleting a HOST record

$ ibHOST.sh -d -h testing
D: "record:host/ZG5zLmhvc3QkLjEuY29tLnNweC5nbG9iYWwuZGUtdGVzdGluZw:testing.domain.contoso.com/Internal%20View"

$ host testing
Host testing.domain.contoso.com not found: 3(NXDOMAIN)

This script has been very handy for most of my data center migrations. Using simple loop iteration to go through a list you can bulk add host records using the Infoblox WebAPI’s. This is not the best script to show off Infoblox WebAPI’s, but it gets the job done. If your looking to use this script, be very careful and test it before any mass runs! I take no responsibility if you damage anything in your environment.


Just an FYI; this script is a modification of a previous post I did in 2012 that uses nsupdate to update A records on a bind server: Quickly update or delete a zonefile host entry.
