  • sudo \/etc\/init.d\/dnsmasq restart<\/span> (for Dnsmasq)<\/span><\/li>\n
  • (for BIND, there are different commands you can try to use)<\/span>\n
      \n
    • sudo \/etc\/init.d\/named restart<\/span><\/li>\n
    • sudo rndc restart<\/span><\/li>\n
    • sudo rndc exec<\/span><\/li>\n<\/ul>\n<\/li>\n
