As of today, November 3, 2023, we have added 6 additional delivery IP addresses to our deliveries.hund.io domain. The 3 original IP addresses are still in use, but now alongside 6 new ones.
Each IP address has an rDNS PTR record pointing back to deliveries.hund.io, so that you may verify our outgoing notification IP addresses.
Our 9 total delivery IP addresses are as follows:
52.25.70.41
44.238.252.68
100.20.163.199
44.239.250.229
34.218.149.126
54.214.129.100
34.211.8.39
18.246.28.182
52.35.144.166
Unless you use firewalls to block incoming SMTP traffic on your network, no action is required on your part. Otherwise, please consider adding this updated list of addresses to your firewalls.
If you have any questions or concerns about these additions, please contact us via live chat, or at support@hund.io .
