Migration of IP addresses for Nexmo SMPP servers 0, 1 and 2
Scheduled for Dec 17, 00:00 UTC  -  Dec 18, 00:00 UTC
Scheduled
On the 17th December 2018 Nexmo will be deprecating the range of IP addresses currently used for SMPP servers 0, 1 and 2.

Hostname - smpp0.nexmo.com
Current IP Address 174.37.245.38
New IP Address 108.168.254.225

Hostname - smpp1.nexmo.com
Current IP Address 174.37.245.37
New IP Address 108.168.254.238

Hostname - smpp2.nexmo.com
Current IP Address 174.36.197.197
New IP Address 108.168.254.239

The new IP addresses shown above are already live today. Therefore we would recommend that you bind either via hostname (which will not change) or the new IP addresses as soon as possible. After the December 17th the current/old IP addresses will no longer be available.

If you are whitelisting traffic in your firewall based on IP then you will need to add the new IP addresses as soon as possible. You must add the new IP address by December 17th to avoid any disruption to your traffic. On December 17th we will be modifying DNS A records to point all of the above hostnames to the new IP addresses.

We apologise in advance for any inconvenience this may cause. If you have any questions about this please don’t hesitate to contact your account manager or submit a support request at https://help.nexmo.com.
