I have a phpBB forum, and I try to ban some indevidual IP's.
But it doesn't seem to ban them.
Am I doing something wrong?
Thanks,
Meir
They may be using a dynamic IP, in which case you will have to ban their IP range (potentially banning some legitimate users as well).

Sorry if this topic is not unique, but believe me, I've searched alot.
I've a website that users can subscribe and have a unique web page for themselves with address like this:
http://website.com/api/username
Now, I want to make them able to access their pages using addresses like this:
http://username.website.com
In fact, username comes here as a subdomain.
and I know I have to add a wildcard a record (* as name and website IP as address). I've made this changes.
But I couldn't find any .htaccess code working for my problem.
could you help me please?
Thanks in advance.
I have seen some sites use hostnames as data such as usernames (for example username.example.com) and was wondering how you would be able to achieve this.
Is it good practice to use hostnames like this or are there reasons against it?
Thanks in advance.
It is generally bad practice to treat hostnames this way. Lookups become a bit more complicated and it is always safest to use usernames in the path or query.
Hostnames are designed to be thought of in a global sense. For instance user.example.com/username/profile
It also helps protect the user (a little) because paths can be encoded into the http request where a subdomain request essentially requests user.example.com and that request can be redirected multiple times before returning to the client and dns monitoring is the number one way that people do tracking.
DNS tracking is easy because its already fast, open, and the contents aren't designed to be hidden like https or more recent ipsec techniques.
I've accomplished this by setting up a DNS wildcard with your DNS host (*.example.com) then using PHP to parse out the username in the URL and act accordingly.
I am designing a pretty big website that will target it's industry on a global level. The site is detecting IP address countries in order to serve content relative to the visitor's country. Basically alot of content will be restricted to visitors in a given country.
The concern I have is that Google doesn't seem to pay too much attention to IP based content, as I read here. They seem to think Google might implement better support for crawling IP based content but aren't sure when and the article is dated Nov 2011.
As a result, I have been considering ways to have Google crawl the site's IP content by country codes like us.site.com or site.com/us still detecting the visitor's country by IP and redirecting to the appropriate location. Im not sure if it's just because I am a little strange at times, but I seem to feel that the subdomain us.site.com seems tidier.
Considering that Google spider ALSO seems to ignore subdomains when there is considerable duplicate content (which may be the case because alot of the content is internationally available), what would you guys recommend?
Should I
Stop being so darn OCD about us.site.com and use site.com/us?
Use subdomains because perhaps while the spider ignores duplicate
content on sub-domains, it won't if there are more unique results?
What about lists of results on my site? Like a category page?
Take a gamble and stick to IP detection only, not using country
codes in the URL and hope for the best that Google will recognise
different content being served on different IP ranges
Thanks in advance
Ok, so i found this which is so far the best explanation I have found, any pointers please feel free to comment
I run this site and I approve access for a section of the site for people. I only want to approve static ips. If i have a bunch of IPs how do I find out if they are static or not? I can do the remaining parts but there is probably some function in the socket library or something that lets me script the part to find if the users are using static or dynamic IP.
thanks !
Php/Js would work too.
There is no way to inherently tell if an IP address is static or dynamically assigned. Based on the hostname that the IPs resolve to, you could probably make a guess as to whether they are static or not, but there is nothing definitive to facilitate this.
You could use the socket module to resolve the IPs to hostnames and flag them as "static" or "dynamic" based on some kind of "best guess" algorithm, but it would be only that: a best guess.
Here is an example using a random Verizon FiOS IP address. This assumes that any IP starting with "pool" is dynamically assigned.
>>> hostname = socket.gethostbyaddr('71.243.222.111')[0]
>>> if 'pool' in hostname:
... print hostname, 'is dynamic'
...
pool-71-243-222-111.lsanca.fios.verizon.net is dynamic
You're going to have a very tough time determining all of the various naming conventions and this would in no way be a complete solution.
You might want to ask yourself what kind of problem you're trying to solve first, and whether filtering access by IP address is providing the kind of verification you need.
I'd use a pragmatic solution: New accounts have a trial phase of a few days. After that they can only log in from the same IP used to sign up. If they still have that same IP it's most likely static.
Well, you don't have a problem, do you? If they ask for access from IP X, you give them access from IP X. If it turns out that it was dynamic and they switch, they no longer have access. In practice, no access from dynamic IPs :)
Seriously though, the authority on IP assignment type is the host from which the user is accessing. Thus, you need to ask the user what it says in his/her config.
I have a client who has brought a truck load of domains he wants me to redirect to his site.
A few of them are the same name with different top level domains (mysite.com, mysite.co.uk etc etc) but a lot of them are keyword related (mylocation-businessType.com etc etc).
I am wondering if either of these will be negative for SEO. I am thinking the top level domain changes will be fine, and expected by google, but the keywords might be views as a bit hacky?
What are the good people of stackoverflow's view on this?
If they are redirected properly then they'll have no effect at all. The only advantage will be if the name makes sense and a user might type it in. eg. identical names with and without hyphens.
For this situation all of the other answers are correct, you won't get any benefits in Pagerank, etc. and it wouldn't be useful except to pickup direct traffic to your domain names that you are then redirecting.
How would it affect your SEO though? That's a little trickier. Two ways of looking at it:
1.) Competitors could do this to you and it'd be completely out of your control. If redirecting a bunch of domains did any real harm to rankings it'd be a great way to do negative SEO, or "Google Bowling," and could be used to take down a site's rankings. That isn't the case though, so it probably wouldn't have too much of a negative effect.
UNLESS
2.) The nameservers for your redirected domains match the nameservers for your main domain. Pointing all domains to the same set of nameservers will help show that all domains are under the control of the same webmaster.
Even if you are using different nameservers and using 301 redirects as recommended, if the server with your redirects comes back to (at least) the same Class C IP address as your main site's server, a search engine would still be able to tie you together as likely being run by the same owner.
Either of these setups can identify you as the source of the redirects and devalue the ranking ability of your main site since there is a much higher likelihood the redirects are coming from you.
winwaed is correct. If you're doing a proper 301 redirect, the other domains are only valuable if people directly type them in. They won't rank, won't get any link juice, and won't get any inbound links. If you do seed inbound links, google will treat them as if they point to the target of your 301 redirect. It's a waste of time to just directly do that for SEO purposes.
The way to use each of those domains for SEO would be to build a bit of unique content on each one, get some inbound links, and then link out to your target page. Not really worth doing unless you really spend a lot of time at it, and google still tends to penalize obvious gaming of the system like that.
They won't contribute toward ranking, however keyword domains do get some amount of advantage for those terms. So, the way to use them is to build sites on all of them and funnel traffic to the main site.
Of course, they can also be used for extra backlinks, but you really want different C class IP addresses from the servers. For that reason you might want to go with SEO hosting.
Matt Cutts from Google explained it in this video:

and here:

He also said if he was doing this, he would redirect each of sites to the target sites' different important pages. If the redirected domains had pageranks before, they will still flow pagerank (not exactly but a lower pagerank).
