What do you mean with "assignment ip"? The assignment of an ip address to a network interface? For that you can start reading about DHCP.

Note: This is not the right thread to talk about this. If you want open a new one.
I think he is referring to public IP addresses.

Yes, we are talking about wan, not lan. cybercontrol need to know how his isp got address so iana (for european people) could be useful.
Take a look even at the addresses class and last ISO/OSI model or tcp/ip model.
This is just 25% that you have to know about networking but it's a good starting point!

I don't see incoherence... for WAN and internet access ISPs use DHCP as well. Our home routers implemet a DHCP client to receive a public IP address and DNS servers from ISPs' DHCP servers.
Correct me if i'm wrong...

wait... your public IP si assigned by your ISP that bought a block of address assigned by autority (like iana), so wan routing protocols are different  to the lan routing protocols and, for example, frame-relay o ppp (the most used with hdlc ) make a kind of authentication (like chap or pap or both) that are completely different to the lan. What I was explain was that your ISP doesn't have a "big dhcp" to assign the ip to the costumers, there is a different structure.

good evening , thank you i have read pila iso/osi is interesting http://en.wikipedia.org/wiki/ISO/OSI
yes ostendali thanks after reading I would like to understand in particular anonymity and geolocation
b4d_bl0ck thanks this..
http://www.rfc-archive.org/getrfc.php?rfc=2939
http://www.rfc-archive.org/getrfc.php?rfc=6195&tag=Domain-Name-System-%28DNS%29-IANA-Considerations

http://datatracker.ietf.org/wg/geopriv/

we would like a guideline for understand among many documents for those who begin, then helps to use better good system as a back box 

Have a nice evening

Oh yes weVeg, sorry.
I knew there is a ppp connection, but i just tought normal DHCP-like operations were executed on the top of it. I never had an in-depth look at that part. Thanks! now i know a bit about IPCP ;)
Anyways i found this one, where DHCP is mentioned and used too, but i need time to read about it.

@cybercontrol
for anonimity you can start reading how tor works, and also something like vpn... But since there are lots of reference to networking protocols, you may consider reading a good networking book. There are some classics which are worthy to be bought, but for free you can gets lots of material online too, like this one from IBM and this guide... and obviously RFCs which sometimes are a bit unfriendly :)

May be some network could use some protocol that provide the use of dhcp on wan, but with our home adsl the ip is assigned in a different way!
Me too I never had an in-depth look so I can make a mistake =)
See ya bro!
