+SSH keys in the network map are replaced with a placeholder value. All IP addresses and domains in the network map follow the same anonymization rules as described above.

+State File
+The state.json file contains anonymized internal state information of the NetBird client, including:
+- DNS settings and configuration
+- Firewall rules
+- Exclusion routes
+- Route selection
+- Other internal states that may be present

+The state file follows the same anonymization rules as other files:
+- IP addresses (both individual and CIDR ranges) are anonymized while preserving their structure
+- Domain names are consistently anonymized
+- Technical identifiers and non-sensitive data remain unchanged

 Routes
 For anonymized routes, the IP addresses are replaced as described above. The prefix length remains unchanged. Note that for prefixes, the anonymized IP might not be a network address, but the prefix length is still correct.
