DNScapy: Powerful DNS Packet Manipulation Program & Library
A powerful DNS packet manipulation program and library for Python used in penetration testing, network troubleshooting, and more
What is DNScapy?
DNScapy is a feature-rich DNS packet manipulation program and Python library for crafting, sending, sniffing, and analyzing DNS traffic. It builds on top of the Scapy packet manipulation framework to provide specialized support for creating, modifying, and dissecting DNS packets and protocols.
Some key features and capabilities of DNScapy include:
- Generating and sending hand-crafted DNS packets such as A, AAAA, MX, TXT, and any type of DNS query, response, or traffic.
- Sniffing and capturing DNS packets transmitted over the network.
- Parsing and summarizing captured DNS traffic.
- Modifying and manipulating fields of existing DNS packets.
- Performance of DNS amplification and reflection attacks for testing purposes.
- A flexible and expressive API for customizing DNS packets at a granular level.
- Built-in support for adding EDNS, TSIG, and DNSSEC signatures.
- Detailed decoding and analysis of DNS packet contents.
- Integrates readily with Scapy for advanced packet crafting and attack simulations.
DNScapy can be a valuable tool for DNS server testing, investigating DNS issues, exploring DNS vulnerabilities, and learning the inner workings of the DNS protocol. Its powerful packet crafting capabilities also lend themselves well to simulating DNS-based attacks for security testing.
