Batch Resolve

Fast asynchronous DNS resolver

Install

Distro packages

There are prebuilt deb and rpm packages for x86_64 you can find within the releases in the list of versions

Arch Linux users can install the package from AUR

Packages install the config file into /etc/batch_resolve.toml

Static binary

Every release binary can be found in the the list of versions. Just place it to one of directories in your PATH (e.g. /usr/bin)

Install from crates.io

If you have rust toolkit installed, you can install batch_resolve with cargo install batch_resolve_cli

Usage

Input and output format is list delimited with new line. Consider such input domains.txt google.com rust-lang.org mozilla.org

Resolve all A records: batch_resolve --in domains.txt --out hosts.txt --query A

Resolve A and AAAA records: batch_resolve -i domains.txt -o hosts.txt -q A -i domains.txt -o hosts.txt -q AAAA

Configuration

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, queries per second amount and retries on failure count ```toml

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", "8.8.4.4" ]

How many queries to perform per second

WARNING: Google Public DNS guaranteed to handle 500 requests per second max

Please make sure that resolve results do not vary with higher request rates

before using high QPS configuration in production.

Alternatively you can use your own local caching DNS server.

queriespersecond = 500

Times to retry on connection timeout

retry = 5 ```

Configuration template can also be found here
