How to configue "Microsoft Loopback Adapter" ?

Question

Hi,
I have Oracle 11GR1,Win XP. with DHCP enabled.
My conputer gets dynamic IP on connection to internet, so i want to install "*Microsoft Loopback Adapter*".
For that i visited this link:
http://download.oracle.com/docs/cd/B1930601/install.102/b14316/reqs.htm#BABGHEFB_
There, in section 2.4.5.3, Installing a Loopback Adapter on Windows 2003 or Windows XP,
step 20,they said to edit host file.
In this step i have some confusion:
>For example:
>10.10.10.10 mycomputer.mydomain.com mycomputer
What to write in above line in place of mydomain.com ?In above example mycomputer is the computer name.In my case
my computer name is user-5ef511de5
so , i wrote
10.10.10.10 user-5ef511de5 user-5ef511de5
This gave unexpected behaviour. That i was unable to connect on DB through any tool.
Please tell what exactly to write in that host file ?
My computer in standalone computer that frequently gets connected to internet via dial up connection.

Yes

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1521)))
The listener supports no services
The command completed successfully
TNSNAMES.ORA:
EARTH =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = EARTH)
)Now, how do you think a connection is going to be established when your listener supports no services??
You may try this:
1. Make a static entry in listener for your database
or
2. Wait for sometime, so that pmon automatically registers the instance with listener
or
3. fire the command: sqlplus > alter system register;
