Home Assistant repeatedly attempting outbound connection to 34.160.81.0

Configuration Frontend

I’m seeing persistent outbound connection attempts from my Home Assistant instance to the IP address 34.160.81.0. I have this blocked at the firewall, but the traffic continues to be attempted at regular intervals.

Environment:
• Home Assistant OS (latest stable)
• Running locally on LAN
• No remote access enabled other than Nabu Casa
• No custom integrations recently added

Observed behavior:
• Repeated outbound connection attempts to 34.160.81.0
• Destination appears to be Google Cloud (based on IP ownership)
• Blocking does not break core HA functionality, but logs continue to show retries

What I’ve checked so far:
• No obvious references to this IP in HA logs
• No known integrations explicitly configured to use this endpoint
• System otherwise functioning normally

Questions:
1. Does anyone recognize this IP as belonging to a known Home Assistant integration or dependency?
2. What is the best way to trace which integration or component is generating this traffic?
• Is there a debug logging approach that will surface the source?
3. Are there known integrations that use Google Cloud endpoints without obvious configuration (e.g., telemetry, speech, updates, etc.)?
4. Is it safe to continue blocking this, or am I likely breaking a feature silently?

Google Translate is baked into Home Assistant for Voice Assistants. I’d assume it’s probably that, but you’re on to something regarding other integrations that could be using Google. They are a HUGE provider in cloud services and DNS services, so that could be highly likely.

The IP is used by Sentry.io ingestion. Ingestion IP Addresses are Changing | Sentry Changelog I believe this is the collection of analytics and crash data, take a look here: DNS requests to sentry.io (SOLVED)

Thanks for the quick response and information!

You might want to mark the post that was the actual solution as the solution rather than your thank you post. It’ll help folks who find this later to know what the answer was.
