Question-DOS commands

[Ghostgirl705]

I was wondering if any of you could tell me about DOS commands. This is for a homework assignment. I normally wouldn't post this but I don't know where else to go or look. And mods if this is not right for the CL please move it...I couldn't find any other appropriate forums

tracert-- the IP addresses it spits out, how can I follow the path the packet took?

ping-- the TTL, what does it start at? At 1 going up or some number going down?

arp--I know that -a will tell me my MAC but what does this and ping and tracert tell me about my IP configuration?

My book has nothing about DOS commands and all the internet sites are such geek speak that I don't understand them.



EDIT: Thank you!!!
