Basic Overview

Set the forward and reverse DNS entries for a host with DNS services provided by Constellix. Supports IPv6 and IPv4.

Super Super Important

As you will see below - this is a slow, very painful process. Constellix's API sucks. If you can use any other DNS hosting service - do it - don't waste your time here. If you are stuck with constellix (like we are) and you find this script useful - great. Please contact constellix and ask them to take their API seriously.

Docker

You can run this inside a docker container:

$ docker run --rm -it -e CONSTELLIX_APISECRET=690dfc33-e457-401e-a1c4-d4a2f1b870b7 -e CONSTELLIX_APIKEY=3a4ffdf9-71e4-4458-94b6-14fd940b81bf ghcr.io/aperim/constellix-hostip/constellix-hostip:latest -vvv example.com

Environment

You must set your consetllix token details in two environment variables.

export CONSTELLIX_APISECRET=690dfc33-e457-401e-a1c4-d4a2f1b870b7 #Use your secret not this one
export CONSTELLIX_APIKEY=3a4ffdf9-71e4-4458-94b6-14fd940b81bf #Use your key not this one

Setting records

python3 ./constellix/host.py --ipv4 203.0.113.1 --ipv6 2001:0db8:0000:0025:0000:0000:0000:0000 example.com

The above would set the following records: 203.0.113.1 A example.com.

2001:0db8:0000:0025:0000:0000:0000:0000 AAAA example.com.

1.113.0.203.in-addr.arpa. PTR example.com.

0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.5.2.0.0.0.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa PTR example.com.

Deleting Records

python3 ./constellix/host.py example.com

Will delete and A, AAAA and PTR records that are set for example.com

Command Line Arguments

usage: host.py [-h] [-4 IPV4] [-6 IPV6] [-v] domain

positional arguments:
  domain                The domain name

optional arguments:
  -h, --help            show this help message and exit
  -4 IPV4, --ipv4 IPV4  The IPv4 address for the domain
  -6 IPV6, --ipv6 IPV6  The IPv6 address for the domain
  -v, --verbose (the more v's the more verbose)

Assumptions

Forward and reverse records can only be set for domains in your account.

Caveats

This is a slow process. Constellix doesn't have any way to find a domain record with a simple search, so we have to look for parts of the domain until we find a match - for IPv6 records - this takes a lot of API requests.

Speed

Further hindering the process is authentication errors with Constellix's API. Over 50% of valid API requests fail against the API with a 401 error. Once Constellix fix this - it will double the speed of these updates. Constellix's API now take 20+ seconds to respond to most requests. Expect updating the forward and reverse records for one domain to take well in excess of 5½ minutes (sometimes up to 20).

NOTE Constellix have still note resolved this issue properly as at Dec 2022
