Methods

InvertDomain(string)

Reverses the order of a domain name's labels: www.example.com becomes com.example.www, a form in which a domain is an ordinal prefix of its subdomains, ending at a dot.

public static string InvertDomain(string domain)

Parameters

domain string

The name, as NormalizeDomain(string?) gives it.

Returns

string

The name with its labels reversed.

NormalizeDomain(string?)

Normalizes a domain name: trimmed, in lower case, and without a leading *., as an entry matches its subdomains anyway.

public static string NormalizeDomain(string? domain)

Parameters

domain string

The name, or null.

Returns

string

The normalized name; empty for a null, empty or white-space name, which matches nothing.
