<br>I have a related but different concern:<br>I don't want a static public IP...I want it to change often. My public IP was 'trapped' by some blog website & given to people, so now everytime I go to related blogs I'm immediately identified. This is a serious privacy issue isn't it? Where's the security? (I block & delete cookies) I called Comcast & was told I had a dynamic IP so it 'should' be changing. I've talked to 4 or 5 people @ Comcast & none of them give me the same or consistent info on public IPs. I have had the same public IP for @ least 3 weeks, (and maybe for years). Again, it is supposed to be a dynamic IP. I was told my WiFi modem assigned the public IP, & to call the router manufacturer...that was not true; they said Comcast sends the public IP to the router. Then I was told by Comcast to turn the modem off for a few hours to reset it, that didn't work; so then they said turn it off for 12 hrs, that didn't work; I 'escalated' my concern was then told by a guy in the Comcast Security Dept. that Comcast has only a limited number of IPs so I'm stuck with the one I've got until someday, in the unknown future, (without anyone's control or knowledge @ Comcast because Comcast has no knowledge or control over the public IPs their customer are 'assigned') that my public IP 'might' change; or if I paid A LOT OF MONEY I could buy my own public IP (no the Comcast Security rep didn't know who I could call for that). I couldn't believe this guy...he was patronizing, lectured me saying that I wanted to know in an hour what took him a year to learn..he blathered on & on with his lecture, saying I was doing 'bad things' & only people doing 'bad things' wanted their public IP to change. He said your public IP can always be 'trapped' by the 'outside world ' (i.e. any/all websites, Facebook, Twitter, gaming sites, etc. etc.) and there is no way to block or protect your public IP and it cannot & will never be changed at my request to Comcast. He said even if I have my own private &/or device IPs it doesn't matter (although I do have them set to protect my systems from being 'compromised') ... but the outside world only sees your public IP and that's that! WHAT? So I called again, the next day/night hoping to get a nice person who had some technical expertise and the authorization to help me ... of course I got a person that said she did not have access to change my public IP, but to call back tomorrow during the 'day' & the 'sales dept.' can & will change my public IP and that it will be dynamic & change frequently, but she doesn't know when or how. Why all these different answers & what it the REAL answer? The 'knowlegable security guy', did say I could go 4G (cellular) and they 'rotate' public IPs all day long. I understand that, and do use my phone & tablet that way when not near a WiFi connection, but data plans are limited, & when I use them on my WiFi they 'squirt out' Comcast's public IP (goto: <a href="

www.WhatIsMyIp.com</a> to see for yourselves)...so if Comcast cannoWhat do I REALLY have & what is/is not protected from the outside world & what can I get changed if I want it changed?t or will not actally give me a truly dynamic public IP that changes frequently, and if there is no way to protect my systems from being identified by the 'outside world' then ... well I need to find an ISP that CAN ensure me of the protection I want...per the United State Constitution? And I'm NOT doing anything 'bad' & I have no problem with any ISP giving a valid law enforcement or governmental agency what they need to investigate my systems @ any time they feel they have a valid security concern. I just don't want any & all bloggers or webmasters to identify me when I'm on the internet, unless I knowingly tell them who I am. So what's the truth about Comcast's public IPs? What do I have & what is/is not protected from who & what can I get changed at my request?
