Outbound SSH Traffic from HP Virtual Connect Blades

We had some readers (kuddos for watching your traffic closely!) report outbound traffic from HP Virtual Connect Blades to 22.214.171.124 on port 22.
No response is received from this IP address, and we guess it is a bug. Interestingly (I think Daniel noted it first), 49, 48, 46, 53 happens to be the ASCII code for 1, 0, . , 5 . So we suspect some buggy code trying to use an IP address starting with "10.5" (in this case, the blade's IP address started with "10.5").
To confirm this guess: If you have an HP Virtual Connect Blade, do you see similar traffic? Is it directed at a different IP address? Does the ASCII rule still apply for you?
