域名备案以前在别的公司务的案,那我可以解析指到别的公司服务器吗

按管局的政策。备案是要跟着空间走的，你解析到哪你的备案就要接入到哪，除解析到境外以外，如果同一个域名有多个接入商，那所有接入商都需要将这个顶级域名的子备案号作新增接入的备案， 如果你解析到别家是短期行为，那你只要原公司不取消你的备案是没有问题的，如果是长期行为还是建议你新的服务商作新增接入的备案

我来和你说，你这样的总是常见的HOST劫持。
找到你电脑的这个文件：C:\windows\system32\drivers\etc 下有一个 hosts 文件（用记事本打开），你看里面是不是有很多的IP呵，可能有一点就是病毒等等。
我给你发一个正常的HOSTS文件内容
# Copyright (c) 1993-1999 Microsoft Corp
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows
#
# This file contains the mappings of IP addresses to host names Each
# entry should be kept on an individual line The IP address should
# be placed in the first column followed by the corresponding host name
# The IP address and the host name should be separated by at least one
# space
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol
#
# For example:
#
# 102549497 rhinoacmecom # source server
# 38256310 xacmecom # x client host
127001 localhost
