FTP Behind Firewall and Dynamic IP Address - ftp

I'm currently working on a client project and I get access to files via FTP. Their server is behind a firewall and they're asking me for my IP address, I'm guessing for whitelisting.
Problem is, my IP address is dynamic and it changes quite a lot throughout the day. Is there anyway around this?
Thanks in advance.

The best way to avoid paying for a static IP is to carry on using a dynamic IP address, but use a dynamic DNS provider such as No-IP which you can cause to update every time your IP address changes (routers will often do this for you automatically, or there are Windows / OSX / Linux (such as ddclient) clients). That way, you can just use something like magpie.no-ip.com instead of an IP address and it will always resolve to your public address.

Changing ip Address Mac

how can I change my ip address on a mac, but without proxies? I've used vpns and have gone to the advanced setting proxy list (using hidemyass etc), but I want a legitimately changed IP address. I've heard terminal can be used, but I don't know how to use that.
An IP address is something your ISP provides your router with. It is not something you can choose.
What you can do is use a VPN to send all your traffic to some server, which then works as a relay.
(And if you're just looking to browse the web anonymously, theres always Tor)

Recaptcha IP addresses

Okay, so we implement Recaptcha in production. We get errors because it can't reach the IP address it needs to use the service. We open a port for the IP address to reach Google. No problem. We do that and configure that IP address explicitly to work. It works great. Then, the next day, we start getting errors again because Recaptcha is using a different IP address. I can allow requests from that IP address, too, but now I'm unsettled. Where are these addresses coming from? How do I configure this to work reliably?
Recatpcha from Google can use any Google IP address and there are lots of them.
Ran this from Windows:
_netblocks.google.com text =
nslookup -type=TXT _netblocks.google.com
"v=spf1 ip4:216.239.32.0/19 ip4:64.233.160.0/19 ip4:66.249.80.0/20 ip4:72.14.192.0/18 ip4:209.85.128.0/17 ip4:66.102.0.0/20 ip4:74.125.0.0/16 ip4:64.18.0.0/20 ip4:207.126.144.0/20 ip4:173.194.0.0/16 ?all"
That's all the network Google uses currently. These can change so check them often.
Google suggest allowing port 80 to all IPs outbound, this highly insecure. They recommend going through a proxy server but again that is highly insecure if your web server is an DMZ. Proxy aware trojans do exist. All that need to be done is exploit a vulnerability to execute arbitrary code and you can create reverse connection on port 80 through a proxy server to download the payload. Then it is trivial to escalate privileges and own the box. I don't mean just Windows servers but Linux as well. I've done it in lab environment on security was on. It's really easy to do.
This is the Google website I got this from:
http://code.google.com/p/recaptcha/wiki/FirewallsAndRecaptcha
I wanted to append to this answer with more recent information. The documentation that Chris is pointing to does not include all of the TXT records necessary to dig (thanks Google):
_netblocks2.google.com (IPv6 subnets)
_netblocks3.google.com (Additional IPv4 subnets)
In my particular case, the _netblocks3 entry contained 2 large /19's that made my initial rule ineffective

Perhaps you should be using a hostname rather than IP

HIding behind a proxy did not seem to work?

I often visit various sites and like to do so anonymously from behind a proxy. However, it seems as if some websites are still able to detect my real IP address. I know this because they use the IP address to attempt to geolocate me for services.
How did they actually get my real IP Address if I am using a proxy?
How can I truly hide myself?
Most proxies you'll find online are so-called 'transparant proxies'. This means they identify themselves as proxy and even give your real IP-address to the site.
These proxies are commonly used to load pages on the proxy-server instead of your PC.
IP proxies won't protect you at all, to be honest.
What you need are VPN's (Virtual Private Networks) a.k.a. Network Tunnel.
VPN's allow you to do everything online via an external PC inside that network. You'll get that PC's IP and all loading etc happens on that PC.
Not all VPN's are undetected. If you always want to browse the web anonymously, you'll need to find some HQ VPN's (barely for free) and you'll need to change VPN frequently.
Try searching on HideMyAss, SecurityKISS, ... or maybe even the TOR-network

Hosting with Static/Fixed IP Address

I have been search for a host that has static/fixed ip address. Right now i use mediatemple's grid server and because it is a shared environment the ip address is dynamic and changes randomly.
My issue is that i have a script on my sever that fetches data from an ftp site. To access the data via ftp, i have to authenticate using an ip address, username and password. Because the ip address is ever changing, i cannot access the data.
One alternative was asking the data company if they would accept a range of ip address or a wildcard but they will not. they will only approve one ip address for download.
The other option was to purchase a self managed server. I do not want to manage my own server nor do i have the expertise to do so. So I need a solution like a shared environment (low cost) with a cpanel but one that has fixed ip address.
Any suggestions would be much appreciated.
You should look for "managed server" or "VPS" solutions.
Which host you choose is up to you. Many hosts offer such solutions, and a smaller host might fit your budget better than a "big name" hosting company.
This is really surprising ... usually in a shared hosting account where your site is hosted on a shared IP, the shared IP address is always fixed it rarely changes. I think you're right now on CDN hosting, so your data delivery IP address varies according to your VISITOR location.
I am hosting my various sites like thewebhostingdir.com and etc at http://www.accuwebhosting.com/ ... on shared hosting and their IP address is fixed since the hosting setup.
I suggest you to change your hosting provider. You don't need VPS at this moment.
I found a solution. Godaddy vps virtual server starting at only $29.

Mac-os-x how to get network details like ip-address, subnet mask,etc

I am new to Mac-OS-X development. I want to get the users Network details just for displaying it in my application. Details such as the IP address, Subnet mask, status whether connected or not, etc.
Is it possible to get the same??
And secondly, Is the IP address different for wireless lan connections and the normal ethernet connections?? I am a little weak at networking concepts.
Any help will be appreciated.
note: I already tried searching the apple developer site for leads but wat i could find is only the System Configuration Programming guide
Strange.. There are no Frameworks or classes to get the IP address... But i somehow managed to get my hands on the following information.. First with this reference.. And secondly i found that..
As mentioned in the link, If we manually set the IP, then it gets stored in the preferences.plist.
But if we set the IP to DCHP, then we can get the ConfigMethod as "DCHP" and hence check the com.apple.network.identification.plist, it'll have the details for the IP address.
Hence with the use of both the plist and checking whether the ConfigMethod is "Manual" or "DCHP" we can get the current IP address albeit this is not documented anywhere.
