Damn if this isn't one of the most off-topic posts ever... |

Anyways, I work in cable modem tech support. He can't access your modem |
| 17 |
directly since it has a private IP address (10.x.x.x), even if he does have |
| 18 |
the MAC address; he'd have to have access to your PC behind the modem (if he |
| 19 |
had your public IP and proper access) or some server that sits on that |
| 20 |
private network -- and have access to the encryption, since cable modems |
| 21 |
encrypt from end-to-end (modem to CTMS, which is basically the cable modem |
| 22 |
system router). So yes, I'd say it's safe to give him the MAC. If he truly |
| 23 |
is a Cox rep, he can pull up your internet account by the MAC address and |
| 24 |
check modem power levels, signals, possible area issues (depends on how |
| 25 |
advanced the software he uses to check this information is). |
