How should I specify the Oracle BGP IP Address for FastConnect Private Peering? The documentation just says "The BGP peering IP address you want to use for the DRG, with either a /30 or /31 subnet mask." Should it be part of the VCN to which the DRG is assigned? Or it could be anything else I choose?
I would always recommend that the BGP peering IPs should be unique in your network and certainly should not be within the range of the VCN you want to attach to your DRG, or indeed any VCN that you might want to reach through the DRG via Transit Routing.
Hope that helps,
Ben

My service is calling a 3rd party service (binance api) and there is a geo location description for US IP addresses (they banned all US IPs). My deployment's region set to Tokyo but the 3rd party services still sees that my request is coming from the US. Is there any solution to get a local ip address to functions where it is located?
You can achieve this requirement by creating a static external IP address in the same region.
To achieve this go through this document which shows how to reserve IP address to a cloud function as it is mentioned clearly what you need to get
In some cases, you might want traffic originating from your function to be associated with a static IP address. For example, this is useful if you are calling an external service that only allows requests from explicitly specified IP addresses.

Just a simple question, it is possible to route a single IP to the default route when this IP is in a range that is already routed.
I have to route this whole range to a certain IP : 10.0.0.0/8
This range goes from 10.0.0.1 to 10.255.255.254
The fact is that we are connected trough a VPN to a server with the IP 10.173.90.171.
Can I make my switch route every IP on the range 10.0.0.0/8 except the single IP 10.173.90.171 and make it go to the default route ?
Many Thanks,
It is possible. You just need to add this specific prefix and point it to the desired gateway. In basic IP networks, routing decision is always performed on most specific entry (10.173.90.171/32). This way you can have 10.0.0.0/8 routed via 192.168.0.1 and then 10.173.90.171/32 routed via 172.16.0.1.
I want to have an IP address which when pinged will load all the data sent from a GPS device. The GPS device is configured to send data to an IP address and port. I need to run a server side script to read the data from that port and display it on the IP address. Does GCP provide a static IP address to be purchased and can I use Google Cloud functions or any other GCP tool to read data from that specific port and display it on that IP address? If yes, how could I go about doing this? And is there any other way to implement this using some other platform?
Does GCP provide a static IP address to be purchased
Yes, you can create a static public IP address in Google Cloud.
Public IP addresses are free when attached to running instances/services.
Reserving a Static External IP Address
can I use Google Cloud functions or any other GCP tool to read data
from that specific port and display it on that IP address?
You have not provided enough information to answer this part of your question.
Do not mix multiple topics into one question. Create separate questions. You will get more/better answers.
I selected my VM zone to be in asia-east1-b but the static I got from generating is from the US? Does google give a IP from the selected region at all?
It's likely that the service you're using to check the physical location of the IP address is checking the location of the IP's owner, Google, rather than the IP itself. In any case, the location of the IP isn't really important as long as the routes work properly.
There are several email servers refusing connections of clients with public dynamic IP addresses. For example many smtp servers receiving emails only accept connections to clients having static IP adresses to avoid spam emails which are directly sent from computers having dynamic IP addresses.
When I looked for answers using google I only found information saying it is impossible to distinguish between static/dynamic addresses. So how do the email servers do it? Are there any databases providing information for specific IP ranges?
Have a look at the MX records of t-online.de (one of the largest German email providers). Try to connect to mx00.t-online.de:25 using Putty (raw mode) on a computer having a dynamic IP address. The mail server immediately closes the connection and does not even allow the client to send any command, while a connection of a server having a static IP is not refused.
Or have a look at the following extract of a SMTP session:
220 mailin.rzone.de [joses mi173] ESMTP RZmta 29.19 ready
EHLO Home-PC
250-mailin.rzone.de [joses mi173] greets 87.179.163.89
250-ENHANCEDSTATUSCODES
250-8BITMIME
250-PIPELINING
250-DELIVERBY
250-SIZE 104857600
250 HELP
MAIL FROM:<sender#example.com>
250 2.1.0 <sender#example.com> Sender ok
RCPT TO:<recipient#example.org>
550 5.7.1 87.179.163.89 is a dynamic IP
This is the email server for customers of Strato, a German hosting company, which also denies access to clients having a dynamic IP address. Email addresses have been changed. I used a recipient address which is acceptable for mailin.rzone.de, so there is no relay issue.
Also http://whatismyipaddress.com/blacklist-check states the following:
Just because the IP is listed with a particular blacklist does not
mean that you are sending spam, just that particular blacklist
suggests not to accept mail directly from that IP address. Most
residential Cable/DSL IP addresses that are dynamically assigned will
indicate that they are blacklisted, meaning you should be sending from
your ISP's mail server, not a mail server running on your own internet
connection.
This is probably the result of using a DNS blacklist based on ISP-provided information about which of their IP addresses are authorized to send email directly. See Spamhaus' Policy Block List for an example.
The information isn't independently discoverable. Participating ISPs must provide the DNSBL services with information about their network.
However, in the case of some of these lists, like Spamhaus, the information is queryable by the general public under certain conditions. You couldn't detect whether IPs are static or dynamic directly, but could still check any particular IP.
You mentioned that whatismyipaddress.com incorrectly lists your current IP address as static. Using their blacklist check tool with your IP, 87.179.190.52, I see that they currently incorrectly show it as unlisted by Spamhaus' PBL (among others). The IP I'm connecting from is both correctly described as dynamic, and listed in the PBL, hinting that that might be what they're basing their information on.
I believe those email servers you're referring to only do a reverse DNS check so as long as you have a PTR record for that IP address, I think it should be OK.
Bottom line, I don't think dynamic IP allocation is an issue with mail servers.
Regarding the question, the only way I can think of is by looking at the WHOIS information, there's a field called NetType. Obviously, you cannot rely on it but at least it can give you an idea if the ISP did provide that information.
Static/public ip addresses are listed by some ISP's as follows
123.123.123.4 static.yourisp.isfine.com
WHILE dynamic are listed:
123.123.123.5 dhcp.mx1.coldservice.com
see?
