XFOR: How to create addresses of form "user@[IP Address]" (193316)
The information in this article applies to:
- Microsoft Exchange Server 5.5
This article was previously published under Q193316 SUMMARY RFC 821 and 821bis compliance requires the support of IPv4
literals (user@[IP address]).
The Exchange Server version 5.5
Internet Mail Service now supports addresses containing IPv4 literals (user@[IP
address]) inbound, outbound, and rerouted. A message is routed inbound if the
IPv4 literal is one of the Exchange Server computer's IP addresses.
A message that is routed inbound is only delivered if it matches a proxy.
However, the Administrator program strips the square brackets from the address
when you try to create an address of the form "user@[IP address]" from the user
interface.REFERENCES Per RFC 821 page 31:
Hosts are generally known
by names that are translated to addresses in each host. Note that the name
elements of domains are the official names -- no use of nicknames or aliases is
allowed. Sometimes a host is not known to the translation function and
communication is blocked. To bypass this barrier two numeric forms are also
allowed for host "names". One form is a decimal integer prefixed by a pound
sign, "#", which indicates the number is the address of the host. Another form
is four small decimal integers separated by dots and enclosed by brackets,
e.g., "[123.255.37.2]", which indicates a 32-bit ARPA Internet Address in four
8-bit fields.
