Is Domain A Record pointing to Elastic IP prone to Attackers?

Currently I have working fine ec2 instance

and the DNS A Record is pointed to my elastic ip

Is it risky to point it on elastic ip? or should I point my DNS A record to my load balancer link?

c – Pointer pointing to another pointer, how to use free correctly?

When I have a pointer pointing to another pointer like:

int *ponteiro1 = malloc(sizeof(int));
int *ponteiro2;

*ponteiro1 = 5;

ponteiro2 = ponteiro1;
free(ponteiro2);

And I'm using the free command (pointer2), so should I deallocate pointer1? If yes, should I do a treatment for pointer2?

seo – How do tools like openlinkprofiler.org work (list of links pointing to any website)?

Google used to have the "link:" tool, but it no longer works.

So how do websites like openlinkprofiler.org or ahrefs.com/backlink-checker work? I mean technology, not how to use it.

Do they explore and index the web themselves?

All database connections pointing to 127.0.0.1

So when updating my computer something weird happened and now my connections to the MySQL database don't work at all anymore.

  1. All of my MySQL saved database passwords have been deleted
  2. I cannot connect to localhost using host 127.0.0.1 and username root

  3. All of my database connections are trying to connect to 127.0.0.1 even if it is not where it should be indicated. I don't know why it tries to connect to 127.0.0.1 when the host is sftp.wpengine.com.

web hosting – Certificates pointing to different places

I moved our website to another hosting company, but I did not want to cancel the old one until the transfer was done smoothly. It now appears that 2 certificates are pointing to 2 different sites. So, sometimes, when the page is loaded, it seems to see an "invalid" certificate and does not load the page, and sometimes it looks like the new one is correct. At this point, everything works. I called the old hosting company and they removed the certificate from my site. But he always seems to charge on the occasion. The new hosting company tells me that it will resolve itself, but it's been 48 hours. I tried to empty my cache, but it does not work. I (and my users) should not do anything to make it all work. What can I do else?

Domains pointing to name servers

Hello,

We plan to change our name servers, but we want to find all the domains that point to our nameservers. I know we could just look at what zone files are on the DNS servers, but I would like to go further and get a list of all the domains pointing to our servers. For example, it may be that a domain has already been directed to our servers and that they have canceled their account, but the name servers always tell us.

Thank you!
