Hi,
Just been allocated 103.247.152.0/22 by APNIC, it would be appreciated if I could get a few of you to _traceroute 103.247.152.1_ and reply back off list, this is my first IP Allocation and I want to ensure there is no retarded routing happening because ISP's haven't updated their route filters. (i.e. national going via San Jose instead of a local IX).
Also if you have the ability to run a _show route 103.247.152.1_, that would be interesting.
As general information, you may want to try this tool
