是否可以为 etc 主机创建规则（规则：10.0.0.* ip。用法：ping ip.10）？

  • 772

如果我有多个主机，我想为其添加别名，例如

10.0.0.10 ip_10
10.0.0.11 ip_11
10.0.0.12 ip_12

有没有办法将这些组合成一行？

我试过了

10.0.0. ip

然后尝试用 ping 它，ping ip.10但它给了ping: unknown host ip.10.

我也试过10.0.0.* ip.*

networking hosts

    不。 的格式/etc/hosts非常简单，不允许进行复杂的模式匹配：

    This  manual page describes the format of the /etc/hosts file.  This file is a simple text
file that associates IP addresses with hostnames, one line per IP address.  For each  host
a single line should be present with the following information:

      IP_address canonical_hostname [aliases...]

Fields  of  the  entry  are separated by any number of blanks and/or tab characters.  Text
from a "#" character until the end of the line is a comment, and is ignored.   Host  names
may contain only alphanumeric characters, minus signs ("-"), and periods (".").  They must
begin with an alphabetic character and  end  with  an  alphanumeric  character.   Optional
aliases  provide  for  name  changes,  alternate  spellings, shorter hostnames, or generic
hostnames (for example, localhost).

    BIND 显然支持这样的东西，以防你想尝试。
