You can use the ioutil.ReadAll function:

import (
    "fmt"
    "io/ioutil"
    "net"
)

func whois(domain, server string) ([]byte, error) {
    conn, err := net.Dial("tcp", server+":43")
    if err != nil {
        return nil, err
    }
    defer conn.Close()

    fmt.Fprintf(conn, "%s\r\n", domain)
    return ioutil.ReadAll(conn)
}
