if i give some one my PC ip address carelessly.do i enable him to find my user name and password?plz advise...

Answer 1

Giving out your IP address does not reveal your username or password. If your system is insecure they may be able to hack into your system and get that but just having your IP does not reveal the info.

Oh to peachsurprize and several others, you don't necessarily get a new IP address every time you reboot your computer. ISPs use DHCP to dynamically assign IP addresses but they generally configure it with a long "lease" period so that you get the same IP address between reboots. In most cases you would have to leave your computer/router (if you have a router, rebooting your computer does nothing as the router really has the external IP address and your PC only has an internal IP address assigned by your router - likely a 192.168.1.x number) turned off for over a week to get a new IP address.

Hi,

Theoritically, no, since the IP address is only your computer's identity on the internet, and nothing more. Even law enforcement cannot gain your username and password (I'm assuming that you are reffering to the Windows Logon username and password). They can only gain the geographic location of your computer and PERHAPS your first and last name.

However, in the hands of a thrifty hacker, an ip address can open you up to a world of danger, particularly exploits like keyloggers.

Unfortunately, not all IP adresses are volitile---many are static, especially when issues by an ISP-given Router. I advise that you make sure you IP address is changed, scan for spyware and viruses, and be careful about answering Spam.

And if it makes you feel better, yes, you can change your username and password. :)

Hope this is helpful.

You should never give anyone your IP address unless they are your network admin. That person that has that information could potentially crack your firewall and mess up your computer or steal files and information from your pc.

Contact your ISP provider and see what they recommend. Perhaps they can give you a new IP Address. You can also try turning off your modem and unplug it and see if your ip address changes. Do an ipconfig command in DOS if you are running Linux or MAC pc then good luck.

Answer 4

If you're on DSL, shut off the modem for a few minutes and turn it back on - it will give you a new IP.

If you're on static Cable there maybe potiental danger depending on the person you have the IP to. Make sure all your firewalls are turned on. You could also request your cable company to issue you a new IP.

The person would have to be really really good to retrive any information from you, I wouldn't worry about it.

Answer 5

Giving someone your IP address in itself is not a problem. But if it's someone you don't know, they may try to use it to connect to your machine, hoping to find vulnerabilites. As long as you keep your operating system and antivirus software up to date and utilize a firewall, you should be fine.

Answer 6

No - ISP's do not give names away without a court order. You only 'lease' your IP address for a set time from your ISP.

Answer 7

It depends on the individual's hacker abilities, but honestly, any one who can do that won't be wasting time stealing passwords. You're almost definitely safe.

Answer 8

Worst case at that specific time, he would know how to try to attack your computer (ping) but you probably renew your ip quicker than he can try and do anything about it.

Answer 9

Not really, everytime you reboot your computer you get a new isp address anyway.

Answer 10

no
