Searching IP Addresses

  • The Approved IP Address tab

    Note:

    The search box has an auto-complete feature that you can use to manually type a CIDR block. In detail, Trend Micro Email Security autocompletes your input based on the CIDR addressing format if you accidentally type only the first several octets of an IP address before clicking Search.

    For example, if you type 16 and click Search, Trend Micro Email Security automatically changes your input into 16.0.0.0/8 and lists all IP addresses whose first octet is 16.
