This is Meraki management traffic.

Doing a lookup of that domain name (for me anyway), it has IP addresses such as 216.157.139.x.

Looking at the Meraki required firewall rules in the dashboard, I can see the subnet 216.157.128.0/20 specified in the categories:

• Meraki Cloud Communication and VPN Registry
• Meraki Insight
• Camera Streaming Proxy
• Backup cloud communication
• Uplink Connection Monitor

its used up to 3xx MB for each logs, just wonder if i can prevent this kind of traffic in normal business hour ? or i can lower the traffic of this ?

Have you done a recent firmware upgrade ? I recall a recent post with similar info.

yep - this was the post:

Re: MR36 - Lots of Traffic to/from Meraki Infrastructure? - The Meraki Community

Pointing to a different URL on this one however.

i called meraki support hotline and they suggested me to upgrade to latest firmware version, so now is in version MR 30.5, i will ask customer to check in their firewall tomorrow to see if the problem still occur, so any solution for this case as i see the post above has not been resolved
