Quoting Greencopper (greencoppermine@gmail.com):I have a firewall with some whitelisted addresses for the kids, one of them is security.debian.org. The firewall flushes the tables with fresh IP addresses using a scripted cronjob with a nslookup that pulls the addresses and automatically adds them to the whitelist. Doing a nslookup on the firewall and on the kids boxes provides the same IP addresses for security.debian.org: # nslookup security.debian.org Non-authoritative answer: Name: security.debian.org Address: 212.211.132.32 Name: security.debian.org Address: 195.20.242.89 Name: security.debian.org Address: 212.211.132.250My whois shows those addresses are in Germany. security.debian.org is in the US.
There seems to be a geographical dependent load balancing DNS server for security.debian.org; maybe that is the source of the OP's problem. From Mexico I get this:
$ host security.debian.org security.debian.org has address 128.61.240.73 security.debian.org has address 149.20.20.6 security.debian.org has address 128.31.0.63 security.debian.org has IPv6 address 2001:4f8:8:36::6 security.debian.org has IPv6 address 2610:148:1f10:3::73 security.debian.org mail is handled by 10 mailly.debian.org. security.debian.org mail is handled by 10 muffat.debian.org.But in a recent thread, another user mentioned a different set of IP addresses; see <https://lists.debian.org/debian-user/2015/10/msg01070.html> and <https://lists.debian.org/debian-user/2015/10/msg01069.html>.
