AioResolver

aioresolver is a fast DNS resolver tool it is capable of resolving over one thousand domain names in 0.2 seconds with accuracy targeting those who seek to resolve a lot of domain names. aioresolver uses python-adns module which provides Python binding of adns that let's you perform DNS queries of your choice.

Features

• Fast: Resolves domain names asynchronously.
• Bruteforce option to find new subdomains.
• Provides option to filter hosts that resolves to same IP address.
• Provides option to use custom DNS resolvers (Default: /etc/resolv.conf)
• Supports A, CNAME, MX, TXT, SOA, NS and PTR query
• Easy to integerate in workflow turn off banner using -s flag to pipe stdout in other tools.

Prerequisite

aioresolver requires python-adns module if you are still using python-2.7 you can install it using package manager.

> apt-get install python-adns

tar -xvf adns.tar.gz
cd adns-1.5.0/
./configure
make
sudo make install

2. Download and install python3 port of adns

git clone --depth 1 https://gitlab.com/kalilinux/packages/python-adns
cd python-adns

Install aioresolver

sudo pip3 install json
git clone https://github.com/tauh33dkhan/aioresolver.git
cd aioresolver

Usage

Flag	Description	Example
-f	File with list of hosts to resolve	aioresolver -f tesla.com
-o	Use this option to save output to a file	aioresolver -f tesla.txt -o alive.txt
-d	Domain to bruteforce	aioresolver -d example.com -w wordlist.txt
-w	Wordlist to use for subdomain bruteforcing	aioresolver -d example.com -w
-c	Resolve CNAME (dedicated arg for CNAME)	aioresolver -f tesla.txt -c
-resp	Use this options to show response	aioresolver -f tesla.txt -c -resp
-query	Query record [A, CNAME, TXT, MX, SOA,NS and PTR	aioresolver -f tesla.txt -query MX
-t	Filter hosts that resolves to same IP	aioresolver -f tesla.txt -t
-i	Intensity - Number of domain names to resolves at once, Default=100	aioresolver -f tesla.txt -i 500
-r	Text file containing list of DNS resolvers	aioresolver -f tesla.txt -r resolvers.txt
-s	Use this option to turn off banner	aioresolver -f tesla.txt -s
--version	Show version	aioresolver --version

1. Resolving Domains

> aioresolver.py -f tesla.txt   

This will resolve domain names in tesla.txt file and returns all the live domains, use -resp option to print A record and -o option to save output in a file.

2. Query CNAME

> aioresolver.py -f tesla.txt -c -resp

This will extract CNAME record of all the domain names in tesla.txt file, use -o option to save output in a file.

3. Query TXT/MX/NS/SOA record

> aioresolver.py -f tesla.txt -query MX -resp

This will resolve MX record of all the domain names in tesla.txt file and the output is given in json format which you can read using jq.

{"host1":["ANSWER1","ANSWER2"],"host2":["ANSWER1","ANSWER2", "ANSWER3"]}

4. Bruteforce

aioresolver provides bruteforce option to find new subdomains.

> aioresolver -d example.com -w wordlist.txt

5. PTR query

aioresolver can be used to extract hostnames from given range using PTR query.

> aioresolver -f rangefile.txt -resp

6. Using custom list of resolver

aioreoslver can be used with custom list of resolvers by using -r flag, by default aioresolver uses resolvers in /etc/resolv.conf file.

> cat resolvers.txt
8.8.8.8
1.1.1.1
9.9.9.9
> aioresolver -f tesla.txt -r resolvers.txt

6. Turn off Banner

> aioresolver -f tesla.txt -s | httprobe

This will turn off the banner so you can pipe resolved domain names to other tools like httprobe
