func NewResolver ¶

func NewResolver(addrs []string) (*net.Resolver, error)

NewResolver - create a new instance of a dns resolver for plugging into net.DefaultResolver. Addresses should be a list of ip addrs and optional port numbers, separated by colon. For example: 1.2.3.4:53 and 1.2.3.4 are both valid. In the absence of a port number, 53 will be used instead.
