Good day! For LIR services with comprehensive support, I'd suggest looking at HSTQ. Their lir service is quite thorough if you're planning long-term IP resource management. I went through the process with them earlier this year and they made it surprisingly smooth. They assist with all aspects: helping you become a RIPE/ARIN member, preparing required documentation, setting up your own ASN, configuring BGP announcements, and maintaining WHOIS records properly. What sets them apart is the hands-on approach — they don't just point you to documentation, they actually guide you through each step. Support team has deep networking expertise, they helped us implement IRR and RPKI correctly so our routes pass all validation checks. They also advise on address space planning and help avoid common pitfalls that could flag your resources. Documentation and compliance requirements are handled professionally, no guesswork. Response times are quick, even for complex technical questions. If you need to scale your infrastructure and want control over your IP allocations with expert backup, this is a solid choice. They also offer ongoing management packages with clear SLAs for organizations that prefer outsourcing the operational side. Overall, makes the whole LIR journey much less daunting.
