From 78,811 reviews, clients rate our DNS Technicians 4.9 out of 5 stars.I’m carrying out some personal research and need a hand tracking down both the correct URL and the corresponding server IP address for a website whose name I already know. I do not have the URL yet, so the first step will be locating the official domain. Once you confirm that, I’d like you to resolve the domain to its public IPv4 (and IPv6, if available) address and supply a quick explanation of how you verified the result. Please keep the process entirely above-board: open-source intelligence methods such as WHOIS look-ups, DNS queries, nslookup, and public records are fine. No intrusive techniques are required or wanted—just accurate, verifiable information. Deliverables: • Verified website URL • Public IP address(es) for that URL • A brief note (...
I have four live WordPress sites—two in healthcare and two in other business niches—that I now need moved from their current shared servers onto a brand-new Cloudways stack. The move has to be invisible to visitors, so I’m insisting on true zero downtime, complete data integrity, and full post-migration testing. Here is what the job looks like from my side: • Copy each site to Cloudways, configure the optimal PHP version, memory limits, object caching, and any Cloudways Breeze or Varnish settings that will genuinely improve real-world load time. • Coordinate DNS changes across both Bluehost (where some of the zones live) and Cloudflare (where the rest sit). Propagate only when staging checks out, then verify SSL certificates reissue correctly. • Confi...
I have a clean Linux server waiting for a full Horde Groupware Webmail Edition deployment. Your task is to turn that box into a production-ready mail system, complete with secure web access, working SMTP/IMAP services, and a short hand-over guide. Key deliverables • Horde Groupware Webmail Edition installed and reachable over HTTPS • MTA (Postfix or Exim—your call) and IMAP/POP service configured, spam-free mail flow verified with external inboxes • SSL/TLS certificate in place (Let’s Encrypt is fine) • One test domain and mailbox created, end-to-end send/receive confirmed • Brief documentation of the steps and configs applied I will supply the distro details, DNS records, and root credentials once we agree on timing. Success is a smooth l...
I have a domain sitting in GoDaddy’s dashboard and a single-page business site template—HTML, CSS and a bit of vanilla JavaScript—ready to go. What I need is for you to make it live on AWS, wire up a working contact form, and ensure the domain resolves over HTTPS without any hiccups. Here’s the flow I’m picturing: • Spin up the most appropriate AWS service (S3 + CloudFront for a static site or a lightweight EC2/Lightsail instance if you prefer), enable HTTPS via AWS Certificate Manager, and configure the distribution so the pages cache properly. • Point my GoDaddy DNS records to the AWS endpoint; a quick walkthrough of the settings you change would be helpful so I can repeat it later if needed. • Drop the provided template in place, confi...

I have a freshly-provisioned VPS that needs to handle all of my domain’s email. The core job is to turn this blank server into a fully functioning mail system that can send and receive reliably while passing modern deliverability checks. Here’s what I need done: • Install and configure the mail transfer and delivery stack on the VPS (Postfix/Dovecot or an equivalent, as long as it is stable and well-documented). • Enable secure access over SMTP, IMAP and POP3 with valid TLS certificates. • Create the first mailboxes and aliases, confirm they work from common clients such as Outlook, Gmail (via external POP/IMAP), and Thunderbird. • Set up DNS records—SPF, DKIM, DMARC and the appropriate A/MX entries—so that test messages land in inboxes...
Title: Setup & Optimization of B2B Cold Emailing Campaign (Instantly or equivalent) Description: I’m looking for an experienced freelancer to help me set up and manage a B2B cold emailing campaign targeting a niche market in France. Context: * I have already purchased an email database (~20,000 contacts) that appears to be of good quality. * I also have the domain names required for sending. * I’ve received positive feedback about Instantly, but I’m open to similar tools if relevant. What I need is not just a technical setup, but a full, reliable framework to ensure strong deliverability and performance. Scope of work: 1. Technical setup * Configuration of email sending accounts (domains, inboxes, DNS: SPF, DKIM, DMARC) * Setup on Instantly (or alternative if ...
My e-commerce site is hosted on Microsoft Azure and three separate problems are hurting sales and engagement: 1) Customers report payment glitches—transactions sometimes stall or throw gateway errors, and a few orders show the wrong totals. I need the root cause identified, patched, and test purchases run to confirm everything reconciles correctly in the gateway dashboard and my database. 2) The on-site search has become unreliable. Some queries return nothing, others take several seconds, and relevance scoring feels off. Please review the current search implementation, optimise the index, and fine-tune ranking so results appear quickly and accurately. 3) I’m running a bulk email campaign, yet most messages are landing in spam. The task here is to audit DNS records (SPF, DKI...
I already have full access to my client’s hosting panel and can supply the log-in details immediately. The first thing I need is a clean backup of the existing WordPress site, moved safely into an /old folder so nothing is lost. Once the legacy site is tucked away, spin up a fresh WordPress install, point it to the current domain, and make sure the DNS or domain mapping stays seamless for visitors. I have a specific premium theme in mind but haven’t bought it yet. As soon as I complete the purchase, you will be able to upload and activate the new theme and carry out any starter configuration it requires. Elementor must be installed and ready for page building. Please also take care of the usual groundwork—permalinks, essential plugins, basic security hardening, and...
I need a turnkey SMTP solution that can reliably handle about 50,000 transactional emails every day. I don’t have a domain or a VPS yet, so part of the job is to source and configure both, then build and secure the mail server from the ground up. Here’s what success looks like for me: • You register or transfer in a clean domain, spin up an appropriate VPS, and install a mail stack (Postfix, Exim, or any proven alternative you prefer). • DNS is fully locked down—SPF, DKIM, and DMARC records propagate correctly and pass common tests. • The server is tuned for high-volume, transactional traffic with solid IP reputation practices (basic warm-up plan, rDNS, TLS, rate limits, queue management). • I can authenticate via SMTP (SSL/TLS, port 465 or 58...
I have the static HTML package for ready to go and the domain is already registered on GoDaddy, yet nothing is live. Here’s what has to happen next, end-to-end: • Set up a fresh Netlify account in my name, using the email I provide. • Upload the existing HTML (plus assets) and verify it deploys correctly on the default Netlify sub-domain. • Generate the correct DNS values from Netlify and update the A/CNAME records inside my GoDaddy dashboard (I can grant temporary access or join a screenshare). • Wait for propagation and confirm both the apex domain and www version resolve to the new Netlify site. • Leave me a short hand-off note outlining where to drop future updates and how to trigger redeploys. Success is simple: typing in any browser loads th...

Description: We are experiencing a critical issue with our domain () where it is not consistently accessible across different users and networks. Background DNS was migrated to Cloudflare on Tuesday 7th April. All DNS records are now managed via Cloudflare. Proxying is enabled for the root domain and www. HTTPS enforcement is configured. This issue has persisted for over 72 hours since migration. Issue Summary Access to the website is inconsistent across different networks: Some users can access the site normally. Some users cannot access it on home broadband but can on mobile data. Others experience the opposite (mobile data fails but WiFi works). Some users receive DNS errors (e.g. NXDOMAIN). Some users receive SSL/privacy errors. This is affecting multiple users across different IS...
