+longgonebn Subscriber² Posted January 13, 2012 Subscriber² Share Posted January 13, 2012 Is there any down side to having a static IP address over a dynamic one? Security wise, or speed wise or anything at all. Based off the knowledge that I know there is not. I just wanted to ask here to confirm before getting one.

sc302 Veteran Posted January 13, 2012 Veteran Share Posted January 13, 2012 no. but why do you think you need one? the only time you really need one is if you are hosting mail. everything else can be handled by a dynamic service like dyndns or no ip. ftp, remote desktop, vpn, other hosting, can all be handled by a dynamic dns provider.

Phouchg Posted January 13, 2012 Share Posted January 13, 2012 Security-wise, static IP can be used to identify a subscriber. Link to comment Share on other sites More sharing options...
+longgonebn Subscriber² Posted January 14, 2012 Author Subscriber² Share Posted January 14, 2012 Good to know :) Thanks guys. And I wanted it so I can setup usenet and other things much easier then DynDNS. I forgot about DHCP Reservations, that is what I ended up doing.

Rohdekill Posted January 14, 2012 Share Posted January 14, 2012 Security-wise, static IP can be used to identify a subscriber. Uhm...so can dynamic. You lease an ip address from the available DHCP pool. It is easy to trace back who had the lease during that time frame. The only difference in the two is that with static there is an "assumption" that the ip is always used by a single device. I say "assumption" because multiple devices can have the same static address, but not in use at the same time on the same network. Link to comment Share on other sites More sharing options...

sc302 Veteran Posted January 14, 2012 Veteran Share Posted January 14, 2012 What does a dhcp reservation have to do with purchasing static ip's? I will tell you what it has to do with, they are not the same. Dhcp reservations are set on your private network. Purchasing static addressing is for your outside so your outside address does not change. Link to comment Share on other sites More sharing options...
+longgonebn Subscriber² Posted January 14, 2012 Author Subscriber² Share Posted January 14, 2012 If I have a DHCP reservation so that I have an internal IP of such and such. My external IP still changes? Link to comment Share on other sites More sharing options...
HardyRexion Posted January 14, 2012 Share Posted January 14, 2012 Yes, Your ISP will periodically change your IP unless you request a Static IP. I think I had to for Xbox Live. DHCP reservations on your router are only for your LAN Link to comment Share on other sites More sharing options...

Email can be hosted just fine on a dynamic IP. The only service I can think of off the top of my head that just isn't good on Dynamic as a basic rule is DNS, which makes perfect sense. But static can help deal with a NAT situation (if your ISP is NATing you and causing a double NAT situation). Although depending on the ISP you might not get a true "static ip" and instead get an extended dynamic ip lease (which could lead to the same double NAT issues).

I say "assumption" because multiple devices can have the same static address, but not in use at the same time on the same network. Tracing a dynamic IP to its leaseholder at a certain time would normally require presenting a legal paper to. In case of internets - an ISP. In case of LAN - the network administrator. Static IP can safely assume that the subscriber (whatever the device or the person using it) will not change. Link to comment Share on other sites More sharing options...
Miuku. Posted January 14, 2012 Share Posted January 14, 2012 Email can be hosted just fine on a dynamic IP. It can but no mail server will ever accept it. All servers I've configured automatically delete any mail coming from a dynamic IP, reduces spam by a good 99%. Link to comment Share on other sites More sharing options...
+BudMan MVC Posted January 14, 2012 MVC Share Posted January 14, 2012 "Email can be hosted just fine on a dynamic IP." Clearly someone that has not had to try and run a email server off dynamic ip range ;) Sure you can get mail all day long, but many domain and lots of major players are not going to accept mail from you.. Use as example because I know they post link about the block when you connect to them for mail ;; QUESTION SECTION: ;aol.com. IN MX ;; ANSWER SECTION: aol.com. 3600 IN MX 15 mailin-04.mx.aol.com. aol.com. 3600 IN MX 15 mailin-01.mx.aol.com. aol.com. 3600 IN MX 15 mailin-02.mx.aol.com. aol.com. 3600 IN MX 15 mailin-03.mx.aol.com. telnet mailin-04.mx.aol.com 25 Connected to mailin-04.mx.aol.com. Escape character is '^]'. 554- (RTR:DU) http://postmaster.info.aol.com/errors/554rtrdu.html 554 Connecting IP: 24.13.zzzz Connection closed by foreign host. "AOL uses the Spamhaus PBL to block mail from dynamic and residential IP addresses. Per our E-mail Guidelines, we do not accept mail from such addresses." Nothing you can do about your IP being in a dynamic range - other than to by a static/work connection from your ISP. Your dynamic assigned IP might as well be static, I have had mine for well over a year without a change. If your equipment is on there is no reason for the ip to change since you just keep renewing the lease. Beside if your on a home type connection, I would pretty much think your ISP TOS says your not suppose to run servers -- not saying all, but most of them do. But yeah dns is another example where dynamic would be a really really bad idea ;) But I think OP is confused between his public IP he gets from his ISP and the ips he uses on his local network, and yes if your going to forward traffic to something on your network then it should be static or have a reservation. If you forwarding say 80 to 192.168.157 you sure don't want that machine to start using .158 after you had a power outage or reboot, etc. Link to comment Share on other sites More sharing options...
MS Bob 11 Posted January 14, 2012 Share Posted January 14, 2012 If you download files from a 1-click hoster like rapidshare, hotfile, fileserve etc, with a static IP you have a waiting time. With a dynamic IP, you just disconnect and reconnect and you can download right away without waiting. Link to comment Share on other sites More sharing options...

I have and do host email (the IP is static currently, but has been dynamic in the past). I am aware of most Dynamic IPs being on an RBL. You can get a "static" ip on your residential account and it could still be on the same RBL. Also, many dynamics are not on that RBL. It depends on the ISP.

+BudMan MVC Posted January 14, 2012 MVC Share Posted January 14, 2012 'many dynamics are not on that RBL. It depends on the ISP." Agreed its quite possible your dynamic ip is not listed in a range - doesn't mean it wont be added tmrw ;) Now your not sending mail to anyone that blocks those ranges. Also without a work static type connection, never heard of a ISP that allows you to change your PTR for dynamic IP they are handing out. Many domains will not accept mail from such hosts. I sure wouldn't -- can not follow the simple instructions for setting up a email server, I don't need email from you ;) BAD BAD BAD idea to try an run an email server for any sort of actual use on a dynamic home type connection. Now if you want to play on how it works, sure go ahead -- but with anything you going to connect to the public net.. Please Please read how to secure it, or more than likely just what the net needs in less than 24 hours a nice shiny new open relay sending spam!
