By default batch_resolve uses Google DNS servers 8.8.8.8 and 8.8.4.4 and retries 10 times on Connection Timeout error. These and Queries Per Second parameters may be altered in configuration file.

Configuration file may be placed in the following locations (priority descending):

batch_resolve.toml
$HOME/.config/batch_resolve.toml
/etc/batch_resolve.toml

Configuration includes DNS servers, maximum simultaneously running resolve tasks and retries on failure count

# DNS servers are only accepted as socket addresses
# If port is not specified default DNS :53 port will be used
dns = [
    "8.8.8.8"
]

# Simultaneous resolve tasks
tasks = 5000

# Times to retry on connection timeout
retry = 5
