messages received in putty what do they mean?

[dragon]

I'm getting the following message in putty every so often:

domainname.co.uk,B,1

and

domainname.co.uk,B,2

What do they mean?

Ah that would make sense - how long for?

And this one?

domainname.co.uk,B,172

When a block is imposed the DAC responds to the first query that is blocked with:

<domain-name>,B,<delay>
