why do you think you have you have IP address traffic on your computer is the first question.

a packet, think of it like a train .... each packet is a box car in the train, between each packet of data.... raw data.... computer bits bytes kind of raw data, binary, each packet has a header and footer which say packet start packet end in the idea of a train... each packet being a box car. the core structure of data transmission developed over time based on the equipment avail then, the packet is the term used to define the raw binary data.

binary data is either 1 or 0, or think of it as ON or OFF, then series of on off sequences is how a computers send or handle all data at the machine level. it only knows on off it does not know map = area defined by detail that translates into blah blah blah... that is higher level application level code that translates on off to everything from color to words to sound

string is a burst of packets
hex is short for hexidecimal which is another way of describing raw data for some programs. think of the computer as based on on off, and everything is layers of translating on off to what is then eventually what you see now as you read this. each key stroke has an address each address has meaning in the translation of on off sequences....

the 'dial up' and WAN ( wide area network) mini port.... conflict. if you already connect to your internet host by way of WAN mini port, you do not need dail up. dial up is using a modem on a telephone line. WAN mini port protocol is using other devices set up to get you connected to the internet.

which comes back to the real question

what are you really trying to do? and really, if you do not know all this already.... this is really the wrong place to ask the question in that (.net) is for programming like carpentry is to building a home, you do not want to be on a carpentry group where every one is talking joists and BTU and building code issues when you only care that your house has doors that lock.... we are talking about framing doors and tricks to align new decks to old houses when things dont fit right, ..... does any of that make sense?

if you want to ask me your real question off line, you can send me a message. I can point you to what and how and all that to solve your core question/issue.
