Scanning by IP 91.199.118.137 (first reported in DShield end September) began early this morning which appears to be testing access to site aahwwx.52host.xyz [2] and currently there is little information available for this host. The scan is alternating between ports TCP/81 and TCP/8088. Domaintools [7] shows the root domain 52host.xyz was last updated yesterday.

The only information currently available for this site is "Welcome to nginx!"
