Two comments on this:
1. It is possible that Android is looking for the DNS search path
provided by DHCP that tells a client what suffixes to try. Looking at the
git repository the XSCE DHCP server may not currently supply this.
I will look into this a bit when I get the chance. The fix if necessary
would be trivial.
2. https://github.com/XSCE/xsce/blob/master/vars/default_vars.yml seems
to imply that the default domain suffix is .local
That is a definite potential bug. While .local is reserved for local
use, multicast DNS clients effectively have taken over this domain to the
point that older networks which have .local DNS entries have run into a lot
of problems.
A network I used to use was like this so I've seen random failures to
resolve things firsthand.
See http://en.wikipedia.org/wiki/.local for more information, although I
do not know of an alternative good practice besides leasing a public DNS
domain name that you know will never be used.

If I'm having trouble with connectivity on a client, I'll try to go to
http://172.18.96.1 in the Browse Activity and see if it resolves. It
usually does, even if http://schoolserver doesn't because something's
borked up. Here's the ifconfig of an ethernet wifi dongle connected to an
AP:

I booted up an XSCE I had been testing with recently and an XO-1 client to
test with. Yep, http://schoolserver and http://schoolserver.localresolved
from the client.
http://172.18.96.1 goes to the portal page, too, of course.
Then I physically unplugged my regular AP so the XSCE wouldn't have any
internet. And http://schoolserver and http://schoolserver.local resolved
on the XO-1 client. Wanted to just make sure that was the case.
But what about an Android tablet? I barged into Tyler's office and pried
the Kindle Fire out of his hands (literally, he was playing Angry Birds),
connected the Fire's wifi to the XSCE, and it got 172.18.100.208. Opened
the Fire's browser and tried to go to http://schoolserver. Hmm, page not
found. Then tried http://schoolserver.local. And that worked! It also
accesses the Moodle login page at
http://schoolserver.local/moodle/login/index.php.
So there appears to be something with the Android browser that doesn't
want to resolve http://schoolserver. So as Curt suggested, try it with
http://schoolserver.local and if that doesn't work, http://172.18.96.1.

I am pretty sure that 172.18.96.0 is the IP address assigned to the
network, and not to any particular computer.
If the network mask is 255.255.255.0 then the .0 address will never point
to a computer or service.
If the network mask is anything else, then I don't know what I'm talking
about.

Just making sure.. have you also tried 172.18.96.1 and/or
http://schoolserver.local ?

Subject: [support-gang] XO tablet can not connect to XSCE server
To: Gang support-g...@laptop.org
The XO tablet can not reach XSCE server. Unregistered XO laptop does
reach XSCE server (http://schoolserver or 172.18.96.0).
The XO tablet WiFi connects and receives IP address (172.18.100.240)
from the schoolserver using its browse or Chrome.
Error message that applies suggest can not find DNS, i.e, can not use
local lookup. The XSCE is not connected to internet.
This seems to be a restriction on the XO tablet, so this may not be an
appropriate question to ask here.
Was hoping that XO tablet(s) could work in MOODLE with created login
account (which works with PC laptop and presumedly with ipad).
