# DNS options There are several options that can be set to configure the DNS server that is used.\ Besides forcing NetExec to use ipv6 there is an option to set the dns server manually, set a dns timeout or to configure using tcp for dns resolution: ```bash nxc -u username -p password --dns-server nxc -u username -p password --dns-timeout nxc -u username -p password --dns-tcp # Use TCP for DNS nxc -u username -p password -6 # Enforce ipv6 ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
