I bought hosting and a domain from the hosting company and they messaged me asking for "name servers for them to point to". I am new to all this DNS stuff and don’t really know where to get these addresses from. Do I need to get them from some public DNS provider or from where? Thanks
So, I am setting up a website to handle shipping services similar to DHL and UPS, but I am also using UPS services to handle the shipping cost through their API to my specific users, and I want to be able to calculate shipping by allowing users to enter a from and to shipping address, and calculate the shipping based on the distance. Any help would be much appreciated.
how can I transform all email addresses in my DB in lowercase?
I did an import and all addresses are uppercase and if a user registers again with lowercase the system thinks is another email. So I want to change all the emails to lower to avoid further duplications.
best will be to have a SQL query to do that
Thanks for your help!
I’m specifically referring to the

As I understand it, MAC flooding is meant to overload a switch’s CAM table, which maps MAC addresses to switch ports.
Where does specifying IP addresses and/or TCP ports fit into this?
Does doing so allow an attacker to bypass a Layer 3 switch’s filters, ones that filter traffic based on IP addresses and/or TCP ports?
I’m trying to understand how my router works so I’m analyzing a couple of outputs (I logged in through SSH). I get these lines when trying
netstat -a -e, and I’m not sure where do these addresses come from, or what they are exactly doing.
The xxx.xxx.xxx.xxx is the IP address that my router gets from the ISP router (WAN).

It is my first time asking questions, so my apologies if there is any mistakes. I sent an email to 2 addresses (2 different departments in same organization with shared @123abc.com), one bounced back from email@example.com due to ‘address not found’. I later found out it was a generated email address. Could someone please tell me if my email was successfully delivered to the other ‘good’ address (the other department)? Thank you very much for your great help in advance.
Long story short I noticed that there are two different IP addresses in the ARP table when I ran the arp check. I suspect my computer might have been compromised because when I ran similar check on my other computer it only returns one IP address instead of two. I’m not running any VPN or anything if it would clear any misunderstanding, it’s why I’m puzzled by this.
I use an “anonymous” mail address (cock.li provider in my case). I have found that mainstream news sites in particular don’t send their newsletters to such an addresses. It looks like the domains blacklisted.
What is the reason? I can understand that they don’t want you writing comments from anonymous mail addresses, but passive reading of a newsletter is also prohibited?
Why this behavior? Why this behavior only with traditional mainstream news?
These newsletters usually have a lot of advertising and tracking, why they don’t wish to deliver them to “anonymous” addresses?
Consider a byte-addressable cache with block size 16 bytes, bytes 0-15 form one block. First I write an int(let’s say 7) to address 0, so now bytes 0-3 contain the int 7. Now if I try to write another int(9) to address 2, then how does the cache handle this? Also if i try to read from byte 1, what effect does that have?
The lectures I’m watching suggest treating a block as the atomic unit in a cache, because keeping track of all the unwritten and written bytes will be a resource heavy task. So how will the above situation pan out? Will every block contain only 1 instance of data, with every write beginning from byte 0? because that is the only possible solution i can think of.
I am currently working on a machine learning module to detect Operating Systems based on existing packet traffic in pcap file format. So far, I have generated some traffic of popular Operating Systems available. However, this process is very tedious.
I would like to know if there is any publicly available pcap files that associates data generated from a particular Operating System (e.g. pcap file that have a lot of traffic from Windows XP). I am aware that there are other similar questions asked regarding publicly available pcap files, however none of them seem to be focused on Operating Systems.
