DNS Server Version Fingerprinting
1 min read
Jan 3, 2026
Exposed version strings reveal BIND or other DNS software details. Match against known vulnerabilities for targeted exploits.
CHAOS TXT Query with dig
┌──(kali㉿kali)-[~]
└─$ dig version.bind CHAOS TXT @$TARGET_IP
Positive response returns the server version in quotes. No response or NXDOMAIN indicates the query is blocked.
Alternative with nslookup
┌──(kali㉿kali)-[~]
└─$ nslookup -type=TXT -class=CHAOS version.bind $TARGET_IP
Same intent; some servers respond differently to nslookup.
