Your RE is matching the local echo of hostname -i\r sent earlier. Try this RE .*\r\n(.*)\r\n#

For example:
Code:
set timeout 3
log_user 0
expect "# " {send "hostname -i\r"}
expect {
   -re ".*\r\n(.*)\r\n# " {set addr1 $expect_out(1,string)}
   timeout { puts "Timeout looking for TCP/IP address\n"; }
}
send "exit\r"

puts "TCP/IP address is: $addr1"

test::expect

Test::Expect(3pm)					User Contributed Perl Documentation					 Test::Expect(3pm)

NAME

       Test::Expect - Automated driving and testing of terminal-based programs

SYNOPSIS

	 # in a t/*.t file:
	 use Test::Expect;
	 use Test::More tests => 13;
	 expect_run(
	   command => "perl testme.pl",
	   prompt  => 'testme: ',
	   quit    => 'quit',
	 );
	 expect("ping", "pong", "expect");
	 expect_send("ping", "expect_send");
	 expect_is("* Hi there, to testme", "expect_is");
	 expect_like(qr/Hi there, to testme/, "expect_like");

DESCRIPTION

       Test::Expect is a module for automated driving and testing of terminal-based programs.  It is handy for testing interactive programs which
       have a prompt, and is based on the same concepts as the Tcl Expect tool.  As in Expect::Simple, the Expect object is made available for
       tweaking.

       Test::Expect is intended for use in a test script.

SUBROUTINES

   expect_run
       The expect_run subroutine sets up Test::Expect. You must pass in the interactive program to run, what the prompt of the program is, and
       which command quits the program:

	 expect_run(
	   command => "perl testme.pl",
	   prompt  => 'testme: ',
	   quit    => 'quit',
	 );

   expect
       The expect subroutine is the catch all subroutine. You pass in the command, the expected output of the subroutine and an optional comment.

	 expect("ping", "pong", "expect");

   expect_send
       The expect_send subroutine sends a command to the program. You pass in the command and an optional comment.

	 expect_send("ping", "expect_send");

   expect_is
       The expect_is subroutine tests the output of the program like Test::More's is. It has an optional comment:

	 expect_is("* Hi there, to testme", "expect_is");

   expect_like
       The expect_like subroutine tests the output of the program like Test::More's like. It has an optional comment:

	 expect_like(qr/Hi there, to testme/, "expect_like");

   expect_handle
       This returns the Expect object.

expect_quit
       Closes the Expect handle.
