Bring your own IP (BYOIP) means your servers use IP addresses that belong to you, not to the hosting provider. You keep them when you move, and their reputation stays yours.
Why use your own IP space
IP addresses from a provider stay with that provider. If you move, every DNS record, firewall rule and allowlist at your customers has to change. With your own space you take the addresses with you. You also decide what runs in your ranges, so their reputation for e-mail and APIs depends on you alone.
Two ways to announce your space
| With your own ASN | Without your own ASN | |
|---|---|---|
| Who announces | You, over a BGP session with us | We announce it from our network AS215120 |
| You need | An ASN and a router or BGP daemon | Only the IP space |
| Good for | Several providers at once, anycast, full control | Simple setups with one provider |
What has to be in place
Networks on the internet only accept announcements that are registered properly. Before your space goes live you need:
| Minimum size | IPv4 /24 and IPv6 /48 are the smallest prefixes most networks accept. |
| RPKI ROA | A signed record that allows the announcing ASN (yours or AS215120) to announce the prefix. |
| Route object | A route or route6 object in the RIPE database, so other networks build their filters. |
| Letter of authorization | Some networks ask for a signed letter that you hold the space and allow the announcement. |
BYOIP at Evolushost
You can bring your own IP space and ASN to our servers and colocation. Tell us your prefixes and whether you use your own ASN; we check the registration and set up the announcement on our network. If you do not have an ASN or IPv6 space yet, we register them for you as your sponsoring LIR, see our RIPE LIR services and the guide on getting your own ASN.
