TCP/IP V6

[Guest]

I had a problem with slow down speed connection on the internet. When I
checked my ADSL routers properties found that both TTCP/IP and TCP/IP
version6 boxes were checked. On unchecking version 6 and re-booting my dsl
connection speed went back to normal.
If I try and use just version 6 I cannot get a connection. The old version
is'nt a problem. So what does version 6 suppose to do.

TCP/IP v6 is supposed to be the next level of TCP/IP. We are currently using
TCP/IP, which is level 4. Apparently, with the expansion of the Internet, we
are running out of IP addresses that can be publish on it. Version 6 is
supposed to give us more IP addresses.

I belive that this is what the changes to verison 6 is supposed to look like:

TCP/IP (v4): aaa.bbb.ccc.ddd
TCP/IP (v6): aaa.bbb.ccc.ddd.eee.fff

IP v4 addresses are 32 bits long. They are usually expressed as four
numbers, each between 0 and 255. 32 bits gives a maximum of
4,294,967,296 addresses. Some of those are designated as unroutable,
some are used for various other purposes. So there are something like
4 billion addresses available. Most of those were given to early
players, since nobody anticipated the explosion that happened. Asian
countries are particularly squeezed for addresses.

IP v6 addresses are 128 bits long. If expressed in the same 0-256
numbers that IPv4 addresses are, there would be 16 of those numbers!
128 bits allows for something like 3.40 times 10 to the 38th power
addresses. Every man, woman, child, TV set, oven, refrigerator, and
anything else you can think of could have its own IP address.

But why should it stop me connecting to the internet?

Hi ib1-2,

The difference between ipv4 and ipv6 is the number of IP addresses that are
available, ipv4 uses 32 bit addresses which are in numeric format, where as
ipv6 uses 128 bit addresses that are in hexadecimal format.

ipv4 type address : 192.168.1.1

ipv6 type address : 2001:db8:0:d802:2d0:b7ff:fe88:eb8a

Currently ipv4 is more commonly used but as you have found out hardware
manuracturers are beginning to add in the ability to use ipv6 addresses as
ipv6 will allow more physical addresses, ipv4 provides us with 4,294,967,296
addresses, ipv6 provides us with
340,282,366,920,938,463,463,374,607,431,768,211,456 addresses. ipv4 and ipv6
can happily exist together.

Hope that gives you an insight to ip and what ipv6 is.

Kind Regards

Whenever you to a site say http:\\www.microsoft.com you computer has to do a
DNS lookup to get the IP address for the site. When you have IPV6 turned on
it will request a IPV6 address for the site. It then will wait until it
times out before requesting a IPV4 address. This additional time waiting for
the IPV6 address to be returned or a time out is what you are seeing.

Hi again ib1-2,

It would probably stop you connecting to the internet because you router
supports ipv6 but your ISP does not.

TCP/IP v6 is supposed to be the next level of TCP/IP. We are currently
using TCP/IP, which is level 4.

Some networks do use IPv6 using routers to bridge to the IPv4 network, as
well as some IPv6 tunnelled links. This isn't something that everybody's
going to magically turn on one night, networks have to adopt it sooner or
later.

Apparently, with the expansion of the
Internet, we are running out of IP addresses that can be publish on it.
Version 6 is supposed to give us more IP addresses.

IPv6, not TCP/IPv6...

I belive that this is what the changes to verison 6 is supposed to look
like:

TCP/IP (v4): aaa.bbb.ccc.ddd
TCP/IP (v6): aaa.bbb.ccc.ddd.eee.fff

That isn't how IPv6 addresses look like. See
http://en.wikipedia.org/wiki/IPv6#Notation for the English explanation.

Thank you all for your responses. The conclusion I've come to regarding being
unable to connect with v6 is my ISP doesn't support it. But I will check with
them along with some other issues I have.
