Use "DNS0x20" to protect against DNS spoofing.

Namespace:  JHSoftware
Assembly:  JHSoftware.DnsClient (in JHSoftware.DnsClient.dll) Version: 1.0.1.0 (1.0.1.0)

Syntax

C#
public bool Use0x20 { get; set; }
Visual Basic (Declaration)
Public Property Use0x20 As Boolean

Remarks

Default value: false

When enabled, the letter casing in the domain name requested from the DNS server will be randomized and matched to response. This improves transaction identity and thereby makes DNS spoofing harder - for details see http://tools.ietf.org/html/draft-vixie-dnsext-dns0x20-00

Note:

This option is not enabled by default because it does not work with all older DNS servers.
