Does this happen each time you connect?

are you using any download or file sharing programs?
I'm on broadband. I'm not using any download or file sharing programs; as far as I know there is only me and ntl.

Following my normal practice of Googling before asking a question, I have just looked up ICMP and found:

"Short for Internet Control Message Protocol, an extension to the Internet Protocol (IP) defined by RFC 792. ICMP supports packets containing error, control, and informational messages. The PING command, for example, uses ICMP to test an Internet connection."

Having battered my head against RFC 3171, I decide to give RFC 792 a miss. However, from the last sentence in the quote, is it simply ntl trying to check their Internet connection to me?
