It's a reserved address, which means that it will never be assigned.
The ISP can still uses these addresses within their internal network.

There is no particular reason why this address wouldn't be accessible.
Can you access other nameservers using nslookup?
Note that using nslookup to query an external nameserver via UDP
requires that you accept inbound UDP packets for any port. If you
block (most) UDP traffic (with ipfwadm etc), you can't use nslookup to
query external nameservers using UDP.

There isn't any how or why. 10.10.1.1 is just like any other IP
address, except that it is guaranteed not to be assigned to anyone.
Consequently, you can use it yourself without any risk of it masking
an assigned IP address.
