func NewBootstrap(s string) *net.Resolver

NewBootstrap returns a customized *net.Resolver which can be used as a Bootstrap for a certain domain. Its Dial func is modified to dial s through udp. It also has a small built-in cache. s SHOULD be a literal IP address and the port SHOULD also be literal. Port can be omitted. In this case, the default port is :53. e.g. NewBootstrap("8.8.8.8"), NewBootstrap("127.0.0.1:5353"). If s is empty, NewBootstrap returns nil. (A nil *net.Resolver is valid in net.Dialer.) Note that not all platform support a customized *net.Resolver. It also depends on the version of go runtime. See the package docs from the net package for more info.
