Because of some disaster I have lost my primary domain controller and thanks god that I had secondary domain controller so I could provide the service to the computer and save my data.
After that I have seized the all 5 FSMO roles to the secondary domain controller and deleted the crashed primary domain controller from Active directory and site and services.
Now I want to have another domain controller to have security in future .
So my question is can I keep the same IP and Host name as crashed domain controller and join the domain and promote it as domain controller or I do need to use another domain name and IP.
Thank you guys for the help.
Any tips will be helpful for me

You can use the same name and IP but as suggested you will need to clean up AD first and remove references to the failed DC.
you can use NTDSUTIL to do this. NTDSUTIL.exe allows you to do a metadata clean up. this way you don't have to go through and manually delete stuff. use the link below, it as all the information you need.
