As stated in Roland's announcement that the Universe Server
(auth.activeworlds.com) will be changing IP addresses, this can present
unforeseen problems . . . I discovered one in my BOT's login code.


The problem with using IP addresses for logging into a universe as opposed
to a DNS is this :

If the IP address of the Universe Server changes, and the IP address for the
Universe was hard set into the source code, people using your bot are all
going to experience login problems when the IP address changes.



My thoughts on working around this problem were originally to add a second
entry box in my Universe Login settings for a DNS value, but then I got to
thinking . . . This is what I came up with :

Have the BOT Program query a Domain Name Server to find the
corresponding DNS for the entered IP (if one exists). If this is done at
the time that the person enters the IP address into the BOT settings and
stored in the registry as an entry called "FAIL- PROOF" or whatever
floats your boat, you'd then have a 2nd resource to fall back on . . .

If an attempt to connect to the Universe Server : 127.0.0.1:0001 returns a
callback other than 0, have it re-attempt a login using the previously
stored value for 127.0.0.1.
Let's call the DOMAIN NAME for 127.0.0.1 LocalHost (since that's
essentially what it is =P).
Now, let's say for some imaginary reason LocalHost has been moved from
127.0.0.1 to : 192.168.0.1
Had we not stored the Domain Name for 127.0.0.1, the BOT would never have
known that the new server is running on 192.168.0.1:0001
Furthermore, the process could be improved even more to change the IP
address in the settings from 127.0.0.1 to 192.168.0.1 automatically.
This in turn fixes any problems associated with my concept to create a
Network Efficient BOT.
Since it doesn't call upon your local Domain Name Server every time you
start up the BOT, you are saving resources on the DNS for more useful things
.. . . Like updating itself =P

But can't we just use "auth.activeworlds.com" ? Please say yes...

I sense you don't understand the point of that . . .

Same here, actually,. I did not get the point... never use I.P. addresses,
just use domain names and you're on the safe side....

but IF someone enters an I.P. address, please NEVER EVER change it
automatically to something you think is what was ment.... an I.P. is a
direct "order" to connect to a certain internet socket endpoint, which
should not be "interpreted" in any way. That is what DNS was made for :)
