My customer wants to know if a Meraki email he received is legitimate or spam. I am looking at the Meraki firewall rules, but I cannot see those IP addresses mentioned in the email. This is the email Hello there, We have updated our Firewall Info page to include new IP ranges to support future growth of the Meraki platform. You are receiving this notice because devices in one or more of your Meraki networks are unable to reach our platform through these new IP ranges. To continue to benefit from Meraki cloud management, it is necessary to open access to these IP addresses in the firewalls upstream of your Meraki devices. If you have multiple organizations please reach out to meraki support to determine what organizations are impacted by this change. What is changing? We are expanding the IP address ranges for Meraki devices to connect to the Meraki cloud to include 216.157.128.0/20 and 158.115.128.0/19. The Firewall Info page has been updated to reflect these new ranges. The first notice about new IP ranges was proactively sent out on February 8, 2022. How are these IP ranges used? The new IP address ranges that Meraki devices will use to communicate with the Meraki platform are within the 216.157.128.0/20 and 158.115.128.0/19 subnets. These IPs are all Meraki owned and operated, and are in the scope of IP ranges that we utilize to deliver our service. This new address pool will allow Meraki to keep expanding its services and coverage of the Meraki cloud platform. What do you have to do? To maintain reliable connectivity to the Meraki platform, please allow the IP address ranges mentioned above in the firewalls upstream of your Meraki devices. If there are restrictive firewalls or ISPs providing internet access to your Meraki devices, please ensure that these connections are opened as per the Firewall Info Page. We recommend that you conduct a full review of all of your firewall rules to identify any that include both of these subnets and update accordingly. Please do not remove existing firewall rules for the dashboard as these new IP addresses are in addition to the old ones, not replacements. When is this taking effect? Connections to the Meraki platform will begin using the new IP ranges from October 1, 2022. Any devices which cannot reach these ranges cannot be guaranteed connection to the Meraki cloud platform, may receive delayed configuration updates, or otherwise may result in a degraded experience. More information about this change can be found here. Please reach out to Cisco Meraki Support if you have any questions. Thank you, The Cisco Meraki Team
