Can google persistent ip ptr resolve to internal address? -

-

amazon has dns option vpc allows resolve elastic ip ptr external , internal addresses depending on query source.

dig @8.8.8.8 ec2-54-194-175-41.eu-west-1.compute.amazonaws.com. +short 54.194.175.41 dig @10.0.0.2 ec2-54-194-175-41.eu-west-1.compute.amazonaws.com. +short 10.0.1.253

google compute engine (gce) ip addresses have ptr 95.141.251.24.bc.googleusercontent.com. not resolve internal ip addresses inside google network. gce has metadata server acts dns , resolves c.project.internal records not elegant above solution amazon.

is there similar elastic ptr gce?

google doesn't provide sort of split-horizon dns service today; you're describing not different ptr addresses, different records public dns , instance dns.

google decided useful able refer other instances name when within network, undesirable information leak when exposed public internet. (internal - nice name, private ip address; external - generic name, public ip address.)

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

-
so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
