Allowlisting our networks
Section titled “Allowlisting our networks”Generally, and especially for the successful use of various services (direct mail delivery via SMTP, monitoring of your systems, DNS zone transfer, general debugging via ping/traceroute), we recommend allowlisting the relevant services from the noris network network in your firewall.
You can safely treat the following networks as trusted and allow them fully for all access:
62.128.1.0/2462.128.9.0/242001:780:6:300::/56
If you still have security-related concerns, please allowlist at least the required services plus ICMP.
DNS zone transfers
Section titled “DNS zone transfers”If you operate a primary (master server) for your DNS zones but want to use noris network DNS servers as secondaries (slave servers), you need to allow zone transfers from the following IP address ranges:
| IP address(es) | IPv6 addresses | Host |
|---|---|---|
| 213.95.0.65 | 2001:780:53d1::53 | dns.noris.net |
| 192.109.102.65 | 2001:780:53d2::53 | dns.noris.de |
| 194.31.2.65 | 2001:780:53d3::53 | dns.noris.ch |
| 62.128.1.0/24 | 2001:780:0:9::/64 | noris network server network |
