G+_Bostjan Cadej Posted May 30, 2015 Share Posted May 30, 2015 Why did you hide your IP? I was just writing you (Fr. Robert Ballecer, SJ) a question why do you hide your external IP in your network tutorials when I saw your last KN show no. 145 where you show us an external IP. Till recently you just showed us internal IPs like 192.168.1.1. Why did you or also some other network tutorials hide their external IP? Does it really matter if I know your IP or I just scan the internet (http://goo.gl/d7kUCb) for any open port, or any other (router/firewall) vulnerability --- and one of hits would also also be your IP. Did you change your firewall dafault password? Link to comment Share on other sites More sharing options...
G+_HoneyBadger411e Posted May 30, 2015 Share Posted May 30, 2015 In 1996 I set a port scanner to scan a massive range of IPs for port vulnerabilities and my parents got a pretty nasty letter in the mail. Have things changed? Link to comment Share on other sites More sharing options...

G+_Eddie Foy Posted May 30, 2015 Share Posted May 30, 2015 Simple port scanning isn't setting off alarms these days. Link to comment Share on other sites More sharing options...
G+_Bostjan Cadej Posted May 31, 2015 Author Share Posted May 31, 2015 On my firewall port scanning isn't setting off alarms, ip is simply black listed ;) Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted May 31, 2015 Share Posted May 31, 2015 It's a reasonable thing to do. They may have an expensive and pretty robust IDS/IPS, but nothing is infallible, and there's no reason to make their IP address known to those who might want to test it.

G+_HoneyBadger411e Posted June 1, 2015 Share Posted June 1, 2015 Jason Marsh That's just common sense. =) I'm not even sure why this post was needed to be posted... Link to comment Share on other sites More sharing options...
G+_Joshua Hamlett Posted June 3, 2015 Share Posted June 3, 2015 Most people are on dynamic WAN (Internet) IPs now which change at various times (depending on ISP settings). And the NAT router/firewall will block most direct attacks. And if you plan on doing anything illegal like hacking, you use a proxy or VPN to mask your external IP address.

G+_Bostjan Cadej Posted June 4, 2015 Author Share Posted June 4, 2015 That is why I was wondering WHY did you (they) need to hide your external IP. Link to comment Share on other sites More sharing options...
G+_Jason Marsh Posted June 4, 2015 Share Posted June 4, 2015 Joshua Hamlett I'd be willing to bet they have a fat pipe and static WAN IP(s) at the brickhouse, as well as some servers necessary to their workflow that are available directly from WAN or via VPN. I have a couple of servers on my LAN that are available to WAN, as well, and even though I don't have anything critical on them or stuff them full of sensitive info, I wouldn't want to make an attacker's task any easier by advertising my IP.
