I love those off-topic messages. Keep it up folks! The more spam the better.

On topic:

If you disconnected and reconnected and still have the same IP then your IP is static assigned by your ISP. If you want to change your IP you will need to call your ISP to change your IP - or ask them to put you on a dynamic-ip pool instead of the static one, so every time you reconnect you can get new IP assigned for you.

Ok for starters how does using a proxy change HIS ip, since its ugly :rolleyes:

What the OP has stated is pretty much impossible -- if he connected a different device (different mac) directly to the modem vs his router (unless he was doing mac cloning) then he would get a different address. So clearly we are not getting all the info.

What your IP address is completely an utterly pointless -- be it ugly or not. This topic has been gone over an gone over.. Its quite simple to change the IP address your ISP gives you -- change your MAC, be it thru the clone feature on your router, or by changing your interface your connecting to your modem.

If your using USB to connect to your ISP -- your pretty much out of luck, an would be at the mercy of the lease time.. Turn off you modem for say 24 hours an hope the lease expires.. If you directly connected to your modem, you can look an see how long your lease is with a simple ipconfig /all command.

That being said -- its utterly pointless to want to change your public IP, unless your trying to circumvent some block some where.

Mando -- you could run pretty much any IP you want on your "private" network that follows IPv4 or IPv6 standards. Keep in mind you would not be able get to any hosts running on the 69.69.69.x netblock depending on your mask on the outside of your network ;) :rofl:

I show that netblock owned by

--

OrgName: Embarq Corporation

OrgID: EMBAR

Address: 500 N New York Ave

City: Winter Park

StateProv: FL

PostalCode: 32789

Country: US

NetRange: 69.68.0.0 - 69.69.255.255

--

So you would not be able to access any hosts on that network ;)

As to the statement "you can't change them. they are assigned to you by your ISP" -- well thats just nonsense now isnt it ;)

Unless you ISP has given you STATIC IP that you have set manually. The IP address given to you will be leased from their dhcp server, which is based off MAC.. If you change the MAC that requests a IP, guess what -- you will get a different IP from the pool.

Almost any NIC driver will allow you to change the MAC.. I have gone over this a few times atleast, posting pictures an examples of how to do it. Google it for many many guides on how to do it. Most common soho routers in use today have a "mac clone" feature which will allow you to set your routers internet interface mac.. So you would get a different IP from your ISP that would work just fine.

That being said -- again there rarely is a point to changing it, nor does it matter what it is really -- unless your trying to circumvent something that has your old IP blocked. As to if the one you have is UGLY or not -- well that would be in the eye of the beholder now wouldn't it.

As to my new mvc status -- yeah was a nice surprise this morning, thanks ;)

Ok that statement couldn't be more wrong, if unplugging the modem and plugging it back in doesn't change the IP it doesn't mean he has a static. Do you even have the slightest clue how DHCP works?

Curious why/how you feel a static is any more helpful than one you got from dhcp?? An IP is an IP is an IP is an IP ;) There is little difference if it was set manually "static" or you got from dhcp/bootp -- be it a "reservation" so you always get the same one based on your mac or just a random one from the pool or not.

There are MANY FREE services out there to keep a FQDN updated with your current IP address. An with most broadband connections being on 24/7/365 its rare that the IP would change anyway, even if just a random one from the pool.

That being said there are quite a few advantages of getting your IP an other info from dhcp. The ISP could change dns that the users of dhcp would auto get when their lease renews. Many different aspects an settings can be handed out via dhcp vs you manually setting the IP (static).

It can allow for the owners of the network to completely change their IP space without having to have user change anything. You can hand out all kinds of useful info -- like the gateway to use, timeservers, the interfaces MTU, static routes, dns search list, arp cache timeout, default TTL, etc.. etc.. etc.. http://www.networksorcery.com/enp/protocol/bootp/options.htm

There are MANY advantages of dhpc over static -- I would be curious to hear your reasons why you feel static is more helpful than dhcp ;) Are you running a name server off this IP? Your in need of a reverse mapping from the IP to your hostname for email reasons? You could not figure out how to map a fqdn to your dynamic IP? What?

Well simply, if I'm playing around with apache on linux on my old box and want the web to see it, a static IP just makes life much easier. Mainly because I'm just doing this to play around and have no clue what I'm doing, so you could be very correct that a dynamic IP would be fine for me.

Offtopic: your tag line is "geeks will rule the world", guess your not going to be a member of the ruling class ;)

EDIT: lant -- what does it matter if your IP has been dynamically assigned or you set it static have to do with accessing whatever your IP is from the public side? You can use any of the many sites that will report what IP you coming from to find out your "public" an then use that to have users on the outside access your website running off a machine on your network.

Off the top;

http://whatismyip.com/

http://www.whatsmyip.org/

http://ipswift.com/

http://www.whatsmyipaddress.com/

http://www.myipaddress.com

VS using the IP address to access your site, which btw would throw out any use of host headers to access different sites off the 1 IP address you have. Or using the normally vey long host name that ISPs assign to the IP -- example: c-xxx-xxx-xxx-xxx.hsd1.il.comcast.net I would suggest you look into one of the many FREE services to map a FQDN to your IP, be it a static or a dynamic one. dyndns.org is a great service for this -- that quite a few routers will auto update the public IP with, or you could manually set.. They allow you have up to 5 names that map to your IP, with many many domains to choose from;

homeip.net

homedns.org

is-a-geek.com

dynalias.com

etc.. etc..

Budman I already have a dyndsn address and use that one all the time, but I didn't think they offered a dynamic IP address updater for linux. I know they do for windows as I've used it before (before I realised I have a static one - so the tool is useless).

edit: just managed to find a linux updater so dynamic would work - but i can't really change that anyway :hmmm:

off topic: Yup I was on telewest so that would be why (and thank god for it - static IP's are so helpful - in my case anyway)

if you mean telewest before the merger then that is now virgin media, ntl:telewest is the business side of things, changing the mac of the device connected to the modem should get you a new ip on virgin media

Before you realised? If you had a static one -- you would of known from the getgo, since you would have had to set it. There is a HUGE difference between a STATIC an a reservation or lease that you have had for a very long time..

My current dhcp address has got to be almost a year old, the one I had before that was well over a year.. Does not mean its STATIC.

If the mac address your presenting to your ISP has not changed, nor has your device that gets the IP have been off for longer than the lease time.. You could be on the same dynamically assigned IP for the lifetime with that ISP, does not mean its "static".

As I already stated quite a few soho routers have builtin in support for updating many of the dynamic IP nameservices out there. dyndns.org being one of them -- this has nothing to do with the OS your running behind the router ;)

But yes -- most of the major players in the dynamic dns would provide clients for many different OSes an routers that support them. For example -- here is the page with downloads for OSX, Windows an linux an hardware that is certified to work with their server http://www.dyndns.com/support/clients/

heheh but that would be so ugly budman man I want 69.69.69.69 externally, ill just do a Mr Remington (if your too young ask your dad wtf i am on about) and buy the corporation lol My IP never changes yet isnt static and is on a 72 hour lease....for some reason it always comprises of 4 sets of sodding numbers (not including subnet range) with dots between them like WTF!! :whistle: I feel the 69.69.69.69 is so unugly and symetrical. I also like 0.0.0.0 (especially when on other peoples PCS heheheh) :woot:

RE: MVC, good to see helpful posters being rewarded I was happy to see the fabled Bud in the line up, its well deserved and overdue matey.

also good to see that at least Budman sensed my sarcasm ;)

I have also had to fudge MAC addresses due to stupid Macrovision FlexLM Licencing servers/dead onboard NICs/HDDs and unhelpful support from certain big corporations who should know better (but thats another story). Its easy if you know how ;)

Peace Bud bro and I hope you have a good festive break ;)

Oh and dont ask how to change (spoof) MAC addresses cos neither me or budman will tell you :)

A bit to late for that -- I have atleast 2 posts where I go over how to change your mac in great detail, with pictures an everything ;) It was not related to changing your IP -- but how unsecure mac filtering is as a means of securing wireless ;)

Already on break -- have been off since the 12th til the 2nd ;) had some vacation days left I had to burn.. hehehe

So your prob seem me on here more than normal even.
