They could be a stealth slave, hidden master, etc. There's no rule that
says that a zone has to be delegated to you for you to be authoritative
for it.
The address of primary-dns.co.uk is adjacent to the address of
auth.primary-dns.co.uk, the server that aaisp.net.uk us delegated to.
They may have all their servers configured as authoritative for all the
zones they host, so that they can use them as hot spares for each other.
