Bind9 DNS Unkown IP address

HI All,

I spent the whole night trying to find why unkown IP address is being added to all news zone files I searched all bind and virtualmin templates & configs but I just cant find where this IP address is coming from and why it keeps getting added named.conf.local ?. I dont have this IP setup within Bind9 or webmin perhaps someone could please help me in what files virtualmin uses ?

Many thanks

zone “new-zone.co.uk” {
type slave;
masters {
81.150.000.000; # This is the correct IP #Hidden for this post
162.13.124.96; # This ip is the rogue one that keeps getting addded on every new zone created?
};
allow-transfer {
81.150.000.000; # This is the correct IP #Hidden for this post
162.13.124.96; # This ip is the rogue one that keeps getting addded on every new zone created?
};
file “/var/lib/bind/new-zone.co.uk.hosts”;
