// WithServer returns the current server handling the request. It returns the

// server listening address: <scheme>://[<bind>]:<port> Normally this is
|
|
// something like "dns://:53", but if the bind plugin is used, i.e. "bind
|
|
// 127.0.0.53", it will be "dns://127.0.0.53:53", etc. If not address is found
|
|
// the empty string is returned.
|

|
|
// Basic usage with a metric:
|
|
//
|
|
// <metric>.WithLabelValues(metrics.WithServer(ctx), labels..).Add(1)
