That IP address is assigned to an ISP run by the phone company in the United Arab Emirates, in Dubai. The IP address is also consistent with those posted on the previous day, which would indicate that it is not a dialup IP but a static or semi-static IP address (i.e. a business or an internet cafe perhaps).
Normally when you dial up you are assigned an IP address randomly from a pool of available IP addresses and it is rare to get the same IP address consistently. If you are on DSL, cable modem, ISDN, T1, or other always-on connection, you tend to retain the lease on the IP address for a set period of time. Either way, the ISP should be able to track the IP address to a user.
Back in early November Sabertooth started archives of Daleel's postings. Daleel was using IP address 194.170.173.50 which was also in Dubai.

Yahoo, Hotmail, and the other freemail providers are nice enough to include the originating IP address in their headers :)
