My boss asked if we can set up a list of IP addresses Zapier uses to connect to our Rest endpoints. So far in my review of the IIS log I found the following IP addresses in use.

3.80.232.5
3.86.222.252
3.87.204.57
3.216.95.101
3.235.101.66
18.205.194.86
18.209.51.139
18.210.7.90
23.22.237.159
34.229.63.201
35.173.47.135
52.207.248.184
54.92.231.121
54.160.9.31
54.197.73.7
54.210.72.144
54.237.200.23
100.25.42.5
107.22.140.57

Although I imagine this list changes frequently and our goal here is to lock down our Rest services so only Zapier and other 3rd parties can connect without having something or someone else be able to brute force their way in from the outside. Has anyone attempted this before and what is the normal way of going about it?

Hi @Arment!

 

We use the dynamic range of AWS’ us-east-1 region, which are subject to change over time. AWS provides some tooling to help your team determine the current IP range of the us-east-1: https://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html

 

I hope that helps!

I am also in exact need of this! Did you ever get an updated list?

You will have to pull the most recent list from https://ip-ranges.amazonaws.com/ip-ranges.json. As Danvers indicated you will have to filter those with service=”Amazon” and region=”us-east-1”.

Also, take a look at the IP subnet calculator if you need the full list of possible IP values for that server’s ip_prefix. 

Best of luck
