python 中實(shí)現(xiàn)單線程綁定域名解析，具體方法如下：

import time
import socket
def ReadHost(file):
  hosts=[]
  ...
  return hosts
def SynResolve(fr):
  hosts=ReadHost(fr)
  IPs={}
  for host in hosts:
  try:
   results=socket.getaddrinfo(host,None)
  for result in results:
  print host, result[4][0]
    IPs[result[4][0]]=host
  except Exception,e:
   print e
  file.close()
if __name__=='__main__':
  start=time.time()
  print 'starting at:',start
  SynResolve('host')
  print 'ending at:',time.time()-start
