[bash help]Adding multiple lines of text into a specific spot into a text file

I am attempting to insert multiple lines of text into a specific place in a text file based on the lines above or below it.

For example, Here is a portion of a zone file.

Code:

                IN      NS      ns1.domain.tld.
                IN      NS      ns2.domain.tld.
                IN      NS      ns3.domain.tld.
                IN      NS      ns4.domain.tld.

        IN    A    255.255.255.255

I need to add 4 lines of MX records in between the final NS record and the first A record, and still leave 1 line of white space between each, so that it looks like this:

Code:

                IN      NS      ns1.domain.tld.
                IN      NS      ns2.domain.tld.
                IN      NS      ns3.domain.tld.
                IN      NS      ns4.domain.tld.

                 IN      MX      mx1.domain.tld.
                 IN      MX      mx2.domain.tld.
                 IN      MX      mx3.domain.tld.
                 IN      MX      mx4.domain.tld.

        IN    A    255.255.255.255

I've checked the other posts which have to do with inserting text into a file, and it seems like this can be done with some iteration of sed, but I'm not sure where to begin. the other examples of this kind of situation on this forum seemed to be dealing mostly with specific line numbers, or a static value to insert the line after. Where in this situation, the final NS record will change, and the amount of NS lines will change from zone file to zone file, so the only static value is the IN NS.

any help anyone can offer with this is greatly appriciated.

radsqlrelay

RADSQLRELAY(8)						     FreeRADIUS helper program						    RADSQLRELAY(8)

NAME

       radsqlrelay - relay SQL queries to a central database server

SYNOPSIS

       radsqlrelay [-?]  [-d sql_driver] [-b database] [-f file] [-h host] [-u user] [-P port] [-p password] [-1] [-x] file_path

DESCRIPTION

       radsqlrelay  tails a SQL logfile and forwards the queries to a database server. Used to replicate accounting records to one (central) data-
       base, even if the database has extended downtime.

       The SQL logfile is created by the rlm_sql_log module. The module must be configured in the radiusd server before you can use radsqlrelay.

OPTIONS

       -?     Print usage help information.

       -d sql_driver
	      Driver to use: mysql, pg, oracle.

       -b database
	      Name of the database to use.

       -f file
	      Read password from file, instead of command line.

       -h host
	      Connect to host.

       -u user
	      User for login.

       -P port
	      Port number to use for connection.

       -p password
	      Password to use when connecting to server.

       -1     One-shot mode: push the file to database and exit.

       -x     Turn on debugging.

       file_path
	      The pathname of the SQL logfile to use.

NOTES

   Oracle driver
       The command "radsqlrelay -d oracle -b db.domain.tld sql-relay" reads the database description stored in $TNS_ADMIN/tnsnames.ora:

       db.domain.tld =
	 (DESCRIPTION =
	   (ADDRESS_LIST =
	     (ADDRESS = (PROTOCOL = TCP)(HOST = db.domain.tld)(PORT = 1521))
	   )
	   (CONNECT_DATA =
	     (SERVICE_NAME = <DB SID>)
	   )
	 )
