Ping uses a protocol called ICMP. Many service providers disable ICMP and many firewalls block ICMP. To see if this is specific to the URL (example.com.tr), ping the address aaa.bbb.ccc.ddd If you receive a notification that the address could not be found, ICMP is likely being blocked. This does not mean something is broken, it has likely been configured this way for security reasons. To identify where that is happening, try using traceroute. If the ping completes, you are likely narrowing this down to an issue with your DNS record.
TYPICALLY, DNS updates are expected completed in 48 hours. Remember this is a process of notifying databases worldwide that there is a change, and that the change is aaa.bbb.ccc.ddd now points to example.com.tr
In the DNS record there are several lines available. As you mentioned an IPv4 address (aaa.bbb.ccc.ddd) You will want to make sure that the address in the A record points to your domain (example.com.tr).
If you have any further questions about this, feel free to ask.
It's almost certainly something wrong. If you post the actual domain name, we can troubleshoot it for you. Otherwise, start out querying the root nameservers to find the nameservers for the TLD your domain is registered in. Then see if those nameservers have your domain's nameservers. Then check your domain's nameservers. – David Schwartz – 2012-08-05T15:38:47.203
