为什么ping虚拟主机的alias0地址返回的不是目标地址？

FinSUN

FB6.1 P10主机，配置如下：
ifconfig_dc0="inet 134.206.224.254 netmask 255.255.255.0"
ifconfig_dc0_alias0="inet 10.10.10.1 netmask 255.255.255.0"
ifconfig_dc0_alias1="inet 10.10.20.1 netmask 255.255.255.0"

在LAN上ping，结果如下：
C:\>ping 10.10.10.1

Pinging 10.10.10.1 with 32 bytes of data:

Reply from 134.206.224.254: bytes=32 time<1ms TTL=64

C:\>ping 10.10.20.1

Pinging 10.10.20.1 with 32 bytes of data:

Reply from 10.10.20.1: bytes=32 time<1ms TTL=64
Reply from 10.10.20.1: bytes=32 time<1ms TTL=64
Reply from 10.10.20.1: bytes=32 time<1ms TTL=64
Reply from 10.10.20.1: bytes=32 time<1ms TTL=64

如上所示：为什么ping 10.10.10.1返回的不是地址10.10.10.1，而是134.206.224.254；ping 10.10.20.1却没有返回134.206.224.254地址？

试下把ifconfig_dc0_alias0 改为ifconfig_dc0_alias3在PING

手册上说只能从alias0开始。
