Wikipedia:Help desk/Archives/2025 January 31#IP block shows a different address

About 80% of the text of the article 4-Hydroxy-1-methyl-4-(4-methylphenyl)-3-piperidyl 4-methylphenyl ketone is taken from a copyrighted journal article. The source is cited and the text is in quotes, but this still seems to constitute a copyright violation as described at Wikipedia:Copying text from other sources. I'm not sure what to do about it though. Can someone knowledgeable have a look? Marbletan (talk) 16:46, 31 January 2025 (UTC)

:The quoted text was added by User:DYLLMARTIN99 in 2018, and that was the only edit done by this account. It doesn't really count as vandalism, and holding a discussion on that account's talk page might not be productive. I think the only course of action that can be taken for now is removing most of the quotes and replacing them with paraphrase. Tutwakhamoe (talk) 19:11, 31 January 2025 (UTC)

When I’m trying to edit a page, I see a colocation web host block for 113.23.0.0/17. Since I’m actually on a residential connection (hotel Wi-Fi in Vietnam), I wanted to request an unblock, so I went to check my IP and got 58.186.*.*, which is not in the blocked range. How do I proceed here? Notpushkin (talk) 16:51, 31 January 2025 (UTC)

:{{ping|Notpushkin}} Are you using a VPN or other anonymising service, even if unwittingly? Those would cause your IP to show up differently to Wikipedia's servers (as your traffic gets routed thru their servers and thus inherits their IP), and would be likely to be blocked on discovery. —Jéské Couriano v^_^v ^{threads critiques} 16:55, 31 January 2025 (UTC)

::Nope. I did have Cloudflare WARP enabled before, but I was getting a different error, so I disabled it. (I think 113.23.0.0/17 is not a Cloudflare network, in any case) Notpushkin (talk) 17:44, 31 January 2025 (UTC)

:In some countries, I've seen them route traffic differently, so while when you go to a check-my-ip sort of website, you might get one result, while going to a different website its routed through a different proxy/VPN/relay. Also sometimes there are other technical reasons which are confidential for how the system detects IP addresses to prevent abuse that are not usually show on simple IP address checking websites, but are available within other technical data. Although with that being said, clearly you were able to post here, so were you trying to edit without being logged in? TiggerJay (talk) 17:41, 31 January 2025 (UTC)

::I’ve checked my IP on the Wikipedia:Get_my_IP_address page, which gets the IP from the Wikipedia API directly (see Get-my-ip.js). So the IP should be the same as when I open an edit page. Maybe it’s some local ISP shenanigans? I’ve just rechecked and I can’t see the block anymore, so it’s either that or a stale cache somewhere. Notpushkin (talk) 17:52, 31 January 2025 (UTC)
