Dear egilutin-ga,
Unfortunately, the original address you cite,
ai-tx-44-72.rasserver.net, returns a 'Host not found' message when
attempting to confirm its DNS information, as does the address you
give below in the comments, d44.ndl-tx.concentric.net.
Looking up information on the domains to which these addresses belong,
on the other hand, has proven more fruitful. According to the domain
registration (WHOIS) records, the former address belongs to ICG
Communications ( http://www.icg.net/ ):

Based on the format of the addresses (common industry practice), it is
almost certain that they are the addresses assigned to machines
dialled-up to one of these ISPs via their modem pools. Combining this
with the areas in which these ISPs operate, it also seems likely that
the particular modem pools these addresses were assigned to are
located in the state of Texas.
However, as these addresses are assigned dynamically to dial-in users,
it is not possible to trace the user of that particular line without
information on the precise time of the connection and access to the
internal logs of the ISPs in question, which are not made publically
available. Thus, unfortunately, the trail cannot be followed beyond
this point.
I hope that this answers your question satisfactorily.
