AS7604 ZETTAGRID-AS-AP Zettagrid Pty Ltd

ZETTAGRID-AS-AP is Zettagrid Pty Ltd, an Australian-owned cloud provider selling IaaS, backup and disaster recovery through IT channel partners, with availability zones in Perth, Sydney, Melbourne and Jakarta.

What it's used for

• Cloud and hosting address space: reverse DNS across 119.252.72.0/22 and neighbouring blocks resolves to IP-ADDR.hosting.zettagrid.net, the naming for its virtual-machine and colocation estate.
• Business internet access for the group's ISP brands. Names like IP-ADDR.cpe.zetta.net.au (customer-premises equipment) and IP-ADDR.static.globaldial.com appear across 202.74.0.0/16 and 203.23.208.0/21, alongside conexim.net and highway1.net.au.

Notable

• This is a single ASN carrying several merged brands. Zettagrid absorbed Zettanet, Highway 1, Global Dial and Conexim; Highway 1 was renamed ZettaNet Pty Ltd and folded into Zettagrid in 2024. The rDNS still carries all of those names, so a name-based read of any one prefix can point at a company that no longer exists as a separate operator.
• The customer base is business and channel-partner, not consumer. The cpe. names are business access circuits, not residential subscriber pools, and there are no dsl-, pppoe- or dynamic-pool patterns anywhere in the space.

Interesting

• The ASN also announces four IPv6 blocks including 2401:400::/32 and 2403:3400::/32, unusually broad IPv6 for a provider of this size.
