DCC server list

I have an old non-stateful router firewall.  Those are particularly
problematic for allowing UDP packets, so my solution has been to
explicitly list all UDP servers I use.

I want to know what I should allow through the firewall for DCC.
I had been using the list of IPs that dcc.rhyolite.com expands to:

dcc.dcc-servers.net.    14400   IN      A       38.144.80.234
dcc.dcc-servers.net.    14400   IN      A       137.118.60.88
dcc.dcc-servers.net.    14400   IN      A       142.27.70.214
dcc.dcc-servers.net.    14400   IN      A       152.20.240.35
dcc.dcc-servers.net.    14400   IN      A       153.19.44.252
dcc.dcc-servers.net.    14400   IN      A       194.85.132.210
dcc.dcc-servers.net.    14400   IN      A       194.109.153.82
dcc.dcc-servers.net.    14400   IN      A       198.137.254.71
dcc.dcc-servers.net.    14400   IN      A       203.147.165.193
dcc.dcc-servers.net.    14400   IN      A       206.169.162.65
dcc.dcc-servers.net.    14400   IN      A       207.195.195.223
dcc.dcc-servers.net.    14400   IN      A       208.201.249.232
dcc.dcc-servers.net.    14400   IN      A       208.201.249.233
dcc.dcc-servers.net.    14400   IN      A       212.69.217.26
dcc.dcc-servers.net.    14400   IN      A       212.95.66.23
dcc.dcc-servers.net.    14400   IN      A       216.240.97.63
dcc.dcc-servers.net.    14400   IN      A       216.244.192.216

However, I then noticed dropped 6277 in my logs.

cdcc info seems to now use a different list:

Note that dcc2.dcc-servers.net are not in the dcc.rhyolite.com list.
Should I instead use dcc*.dcc-servers.net?
