About the DreamHost IP range data

  • ASNs and holders

    DreamHost announces its prefixes from AS26347. Holders in the registry: AS26347 (DREAMHOST-AS - New Dream Network, LLC).

  • What the list contains

    The ranges are the prefixes these ASNs announce in the public BGP routing table (obtained through RIPEstat), with adjacent blocks left unmerged. This is not an ownership record: it can include prefixes of customers and leased address space, and it can miss routes that very few peers see. Snapshot of 2026-11-02.

  • Typical uses

    Allow or block traffic from DreamHost in a firewall, WAF or nginx, label source IPs in your logs by network, or test with a CIDR match whether an IP belongs to DreamHost. Remember that cloud and carrier address space also runs the services of customers, so blocking a whole network can hit unrelated sites.

How to use the DreamHost IP list

  1. Start with the tables above: one for IPv4 and one for IPv6, each row with CIDR, start IP – end IP and address count.
  2. Choose Download TXT or Download CSV for the complete list. The file has all 23 ranges, not only the first rows shown on the page.
  3. Import the TXT as one address set into your firewall, router or ipset, or paste the CIDRs into a cloud security group rule.
  4. Check the snapshot date (2026-11-02) before using it in production. Cloud ranges change often, so compare with the official range file published by the provider.

DreamHost IP ranges: frequently asked questions

How many IP ranges does DreamHost have?

As of 2026-11-02, DreamHost announces 20 IPv4 prefixes covering 168,192 addresses and 3 IPv6 prefixes in the public BGP routing table, through AS26347.

What is the ASN of DreamHost?

DreamHost uses AS26347. Holders in the registry: AS26347 (DREAMHOST-AS - New Dream Network, LLC). Large organisations often run several ASNs, and this page merges the ones listed here.

How do I use the DreamHost IP list for a firewall allowlist or blocklist?

Download the TXT file (one CIDR per line) and import it into ipset, nftables, an nginx allow or deny include, a router address list or a cloud security group. Import the 23 ranges as one address set rather than as separate rules. The address space of DreamHost also hosts the services of its customers, so blocking all of it can cut off unrelated sites.

How often is the DreamHost IP list updated?

The list is a snapshot of 2026-11-02, regenerated about once a week from public BGP data (RIPEstat). Announcements change every day, so download it again before using it in production, and for cloud providers also compare it with the official range file they publish.
