Validator: validate fqdn fails if the domain name starts with integer number

[deschmih]

Package version eg. v8, v9:

v9

Issue, Question or Enhancement:

If a fqdn starts with an integer f.e. "0.de.pool.ntp.org", the validation fails. The example "0.de.pool.ntp.org" is a valid ntp-server (see https://www.pool.ntp.org/zone/de).

Code sample, to showcase or reproduce:

package main

import(
    "fmt"
    "gopkg.in/go-playground/validator.v9"
)

type SettingsNtp struct {
    NtpServer string `json:"ntpServer" validate:"required,ipv4|fqdn"`
}

func main() {
    validNtp1 := SettingsNtp{ NtpServer: "de.pool.ntp.org"} // valid ntp-server see https://www.pool.ntp.org/zone/de
    validNtp2 := SettingsNtp{ NtpServer: "0.de.pool.ntp.org"} // valid ntp-server see https://www.pool.ntp.org/zone/de

    fmt.Println("validator fqdn")

    validate := validator.New()
    errs := validate.Struct(validNtp1) //this validation is succeeded
    if errs != nil {
        fmt.Println(errs)
    } else {
        fmt.Println("No errors validNtp1")
    }

    errs = validate.Struct(validNtp2) //this validation fails
    if errs != nil {
        fmt.Println(errs)
    } else {
        fmt.Println("No errors validNtp2")
    }
}
