hi all i am wondering if anyone can help because I am a little stuck with this one.
We are in the process of moving our address space from a PA block to a PI block. This means I have had to use 2 new IPs for our name servers. the old address space was 89.221.36.0/24 and the new address space is 91.213.52.0/24 the old name servers we on 89.221.36.20 and 89.221.36.30 I have now updated the records and we use ns1.upstreamsystems.com on 91.213.52.20 ns2.upstreamsystems.com on 91.213.52.30 I made these changes about 2 weeks ago at which time i had very aggressive TTL and minimum values set. My aim being to have the changes updated within the Internet quite quickly. The problem I have is that I am still receiving many DNS requests on the 89.221.36.20 and 89.221.36.30 IPs even though my queries out on the net all say the new IPs are in use. Furthermore, if i stop my name servers using the 89.221.36.20 and 30 and then block traffic to these on the firewall DNS lookups from remote hosts stops working! (e.g. dig ns1.upstreamsystems.com A times out) perhaps the root or top level servers have still the old data cached? is this possible? does anyone have any ideas? thanks mike -- Mike Dilworth Upstream S.A.
