最近看到很多人收到hostmonster主机商的一封奇怪的邮件，邮件内容如下所述

Upcoming Changes to Your Dedicated IP Address

HostMonster.Com customer,

HostMonster.Com is making a minor change to accounts with a
dedicated IP address. This change will affect all customers making
outbound connections from their account.

Previously outbound connections came from the shared IP address of
the server (74.220.215.64). This IP was provided for whitelisting
to other HostMonster.Com accounts, third party hosting
companies and credit card processing services.

Beginning Feburary 22th, 2011 at 2 PM MST, all outbound connections
will come from your account’s dedicated IP address (67.222.49.156).
Please provide this IP to any services that require whitelisted IP
addresses.

…………………………….

大致的意思就是说以前的外部连接ip地址由74.220.215.64变动到现在的67.222.49.156了，

这只是一封告诉我们ip发生了变化，我们不需要进行任何的操作。所以希望有收到这样邮件的的人不要紧张。
