Invision Community 4: SEO, prepare for v5 and dormant account notifications Matt November 11, 2024Nov 11
Posted November 17, 20186 yr I can see in my online users list a lot of guests (15+) coming from the same/similar IP. What do you guys think this might be? Should I be concerned? Should I block the IP? Has anyone come across this type of situation before? Any advice would be much appreciated.
November 17, 20186 yr https://whatismyipaddress.com/ip-lookup, amongst other tools. 🙂 Most of those appear to originate from France, I'd not (personally) be massively concerned about that unless it gets out of hand. Do you have a robots.txt present ? I'm thinking of something like a crawl-delay parameter here: User-agent: * crawl-delay: 30 (or 60 perhaps) its seconds I think some bots ignore it though, but it may help if you don't have one at all...
November 17, 20186 yr If they don't slow down my site I do no action. Some weeks ago there were bots causing heavy impact on my server load and I blocked the IP's in ACP. 2 hours ago, AndyF said: I'm thinking of something like a crawl-delay parameter here: Thanks for the suggestion, didn't know you can add delay parameters. I just read some sites regarding this and this can slow down site indexing if you have a lot of pages to index. And not all bots will follow this parameter.

You'd need to use their webmaster tool set to introduce a delay to slow this one down although its not usually a cause of concern I found. 🙂

Though interestingly, they show as being a block of "Failover IP's". Not certain what that phrase means, but personally I'd just block the range of 54.36.148.0 to 54.36.151.255 if that happens again. (It may be a rogue search engine.) In CIDR format that would be: 54.36.148.0/22

November 20, 20186 yr I don't believe CIDR format can be used in the software ban settings, however you can use 4 separate entries with wildcards. 54.36.148.* 54.36.149.* 54.36.150.* 54.36.151.* But this really should be done on the server level, in the server Firewall, so that they don't even see a "You aren't permitted to visit" error. An .htaccess file can be used as well, but the firewall is preferred.
