Let me tell you, searching for typical tech support issues, ehow is always on the first page and the content is clearly spam- usually only tangentially related to the query. try Googling exchange server specify IP adress- and try to find something useful.


sort by: page size:

Since they do content based filtering (sending a RST if they don't like the contents of your packet) the actual IP address of the server returning search results is irrelevant.

IP ranges used for VMs are often problematic. I wouldn’t recommmend them for outgoing mail. See: https://news.ycombinator.com/item?id=7634890

Those entries aren't all singular IP addresses. Some are ranges (etc).

Picking one at random:

That's showing a fair number of IPs.


Office 365 sends your IP-address by default in the X-Originating-IP e-mail header. See here how to remove the IP from you e-mail header http://community.office365.com/en-us/forums/158/t/20470.aspx

The IP search is a great and super simple work around. Thanks a lot for that suggestions!

Gmail has NEVER included the IP in headers (you can easily check this yourself). Hotmail/Outlook on the other hand ...

Do you have a fixed or dynamic IP? When I tried sending email from my home network (which had a dynamic, if long-lasting IP), I discovered my ISP's addresses where on the PBL[1] and therefore getting rejected by many servers. This was in Europe, not the US.

I think this is a spammy neighbour problem on that sending IP. Might be you, might be someone else who's using SES. But whoever sends from this IP is penalised.

It's not "your" IP address, it's DigitalOcean's IP address. And DigitalOcean is unwilling or unable to police their IP address space, so you've been lumped in with the other bad actors inside 45.55.0.0/16.

There are lots of hosting providers that actually respond to abuse reports, and thus have good email deliverability. DigitalOcean isn't one of them. (I say this as someone who has repeatedly reported spam and malware C&C to them, and AFAIK those reports went to /dev/null.)


It does not help.

It seems like Google decides what to show by IP address - not sure if it based on history of queries from that IP address or based on location of IP address. The same query from my college's day work (just a couple of miles away) gives different results.


It’s not about IP addr; I live in Sweden but don’t speak much Swedish. Searching for things takes me to Swedish sites.

Quite frustrating honestly.

(Another related thing that’s frustrating is people using my IP to determine language instead of the Accept-Language header my browser sends)


When I google “my ip”, I get a onebox showing me my IP. Dose that not appear in your search results?

Maybe some sites just check the User Agent, not the IP.

"Sir, please type this into your browser to get to the router web interface: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. I repeat 2001:0db8:85a3:0000:0000:8a2e:0370:7334."

"Server IP address could not be found."

5 minutes later...

"Now could you please tell me the IPs of all connected devices?"

Customer hangs up and cancels his subscription.


I've added the non-working IP address into the original reply in case that's of value.

I don’t think most users realize that their home IP may well be reversible back to a mailing address, nor that commercial IP-to-mailing address databases exist. If an end user has routinely submitted their physical address in Web forms, it’s probably in one of these databases.

For customers of Comcast and many residential broadband providers, DHCP hands out a hardcoded per-customer or per-CPE IP, not the next available address from a pool. For all intents and purposes, the DHCP-assigned address is static.

At least as of a year ago, Comcast support won’t let customers change their effectively-static “dynamic” IP.


Can anyone explain how to read this?

The article appears to be paywalled if you have previously visited their website or more likely your IP has visited in the past month.

Website seems to be only loading the first page and then using an XML request to pull the rest of the article down after a server side check.

I rarely get to read articles from places that do this because it always says I've reached my limit despite not having visited. Pretty sure they base it on IP which any technical person would know IPv4 gets rotated regularly between ISP subscribers.


IP Lookups are incorrect

Ex : India.gov.in [from suggestions] is on 164.100.129.97 / Page traces to some IP in China (Hysterical)!
